Hooniverse Asks- How Important is Your Exhaust Note?

She’s got a competition clutch with the four on the floor. And she purrs like a kitten till the lake pipes roar. If anybody knows sound it’s the Beach Boys’ Brian Wilson. And he celebrated a certain sound – that of the ornery growl made by a flathead mill – in the cruise night classic Little Deuce Coupe. 
Exhaust notes come in all shapes and sizes, from the whisper quiet exhalations of the Prius hybrid to the bone shaking wail of an F1 car at full chat. But how important is your car’s gastriloquism? Cars make a lot of sounds, and sometimes having one drown out all others can hinder your ability to detect potential problems. Some cars give you a choice of noise- with cut-outs allowing both stealth mode and wake the neighbors.
The primary functions of the exhaust system are maintaining proper back pressure to ensure efficient gas flow, turning percussive internal combustion into a non-deafening tone, and guiding potentially deadly gasses to the driver behind you rather than in your cabin. For some folks, you can add sound like a fat swarm of fat angry bees to that list. That, however is not a universal demand.
What’s your take on your exhaust sound? Well, not your personal exhaust, that opinion’s practically a given – if you’re a dude you take great pride in sustained multi-octave personal exhaust, while everyone knows girls don’t fart. But what about your car, is its exhaust note important to you, and if so do you swing to the fart can end, or do you prefer your car to be SBD?

    now this is a good one for me right now.
    for those who dont know i will soon[-ish] be the owner of a mx5. ive considered adding a more aggressive exhaust note to it. sadly the replublic of california wont let me muddle with the mid pipe as i understand the situation. but why bother only replacing the muffler?

    1. dukeisduke Avatar

      I remember when the MX-5 first came out, and reading about how the Mazda engineers toiled over the exhaust system design, trying to get just the right note.

      There has to be a CARB legal cat-back system. I had a hard time picking what I liked best on the Miata. They all get raspy as hell on the top end, and only the more expensive ones had a good deep tone through out.
      But at the same time, I found the stock one on my '90 to be loud enough, as loud 4 bangers are typically annoying.

    3. gochomoe Avatar

      There are lots of them available. If you do some looking around and find the names you can search youtube for the actual sounds. I have a Thermal exhaust on my 94 and it sounds wonderfully low. I've been asked if I have a v8. Replacing just the muffler makes it sound nice plus it free's up a few hp on the high end. Helps for the highway gas mileage. I get about 40mpg at 80mph.

    4. dolo54 Avatar

      There are definitely street legal cat-backs available. As long as the readings are under limit the inspection does not care what brand of exhaust you are running. I've passed inspection for a couple years now in CA with 2 different exhausts on my car. One was an old cheapo that I bought the car with. And now a new one which also passed with flying colors. Both systems were loud (although the new one is a touch milder, but still loud). <img src="https://specialtyz.com/shop/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/d/u/dualtipcatback.jpg&quot; />

    i don't have an exhaust not to be proud of (currently)… and my current vehicle was called the "thunder-van" for a while because of a missing gasket between the manifold down pipe and cat. 4.3L v6 didn't sound good. my 96 T-Bird sounded good though (4.6L v8) with X pipe dual exhaust sounded very good… other than that… I love the sound of a turbo diesel. doesn't matter what size. 1.9L VW up through 6+L cummins…. best note ever

  4. OA5599 Avatar

    More important then the actual note is the ability to set off car alarms with a blip of the throttle.

    1. chrystlubitshi Avatar

      you should get multiple thumbs up for that (i can only give you one) I have driven (to park) a number of cars that set off car-alarms either due to exhaust or sound systems. and that is always a good feeling…. especially when it's due to the engine.

      I enjoyed that when my header broke open, and I was waiting on a new catalytic converter to show up in the mail so I could get it fixed.
      Went out to eat, parked in a parking garage. Parking garages are fun to do pulls through because of how much everything echoes off the walls, but its even more satisfying to do a pull, have it backfire when you let off, and while you are coasting down hearing five or six car alarms.
      Also satisfying when you have road rage and you pass someone at WOT.

    4. gochomoe Avatar

      This used to be my favorite weekend pastime. All the hotrods would find a car with an over sensitive alarm and keep cruising past. We once drained the battery of a Porsche over the course of 4 hours or so of cruising.

    Depends on the car. Cat-back duals on the pickup would have been nice but weren't worth the added expense – it's a workhorse, not a showpiece.
    On the other hand, the aural symphony is a critical component of the Alfa experience. Headers + Ansa tip helped sweeten the note, now I'm thinking about replacing the muffler with a straight pipe.

    1. chrystlubitshi Avatar

      DO EEEEET. straight pipes sound beautiful at any rev level.

    2. dukeisduke Avatar

      I call cat-back duals on pickups "bubba pipes". I always dig it when one of the tailpipe hangars come loose, and the pipe bounces up and down while the truck is moving.

    3. Alff Avatar

      Optimizing for sound can be detrimental to performance, though. Although not about exhaust, that's the reason I didn't replace the stock airbox with the aftermarket cold-air intake I acquired with a parts car. The aftermarket intake adds a nice sound but the combination of smaller surface area and the fact that it draws heated air from inside the engine bay results in fewer horsepowers.
      If anyone is looking for a conical intake for an 2.0 Alfa Nord, I have a spare.

    The 289 breathing through long tubes and non crossed over 2.5" pipes dumping through Flowmaster 40s right in front of the rear axle sounds amazing. In the car you really only notice it when you open the secondaries up on the carb. From outside it burbles great at idle and gets raucous as you hit the gas.
    My VW also sounded great. I cammed out the 1641 just a wee bit so it had some awesome lope. The exhaust was a 4-into-1 collector with a 2 foot straight pipe sticking straight out the back like a bee stinger. The surprising thing is how quite it was inside the car. Most of the sound was directed straight back. However when backing in to my parking lot the sound echoed off my house. It sounded great. Like an angry wasp almost.

  9. Smells_Homeless Avatar

    The sounds a car makes, not only the exhaust but also things like the tick of the injectors or whine of gears, is absolutely crucial to my enjoyment of the experience. I've always said that if something happened and I lost my hearing (oh please no!) I'd probably stop playing with cars altogether.

      whenever the question is asked… "which would you rather lose, hearing or sight??" i always choose sight. i need sounds. sounds can lead you through everything… i'd rather be blind than deaf. no offense to anyone who might take any kind of offense tho that…

    The Z3 has a loud exhaust, it can be rather droning while driving. It was that way when I bought the car. I think it just has a couple of resonators impersonating mufflers. It does sound really sweet above about 4,000rpm though.
    Personally, I don't think I have ever bothered to modify an exhaust system for sound. I did switch my 77 Corvette over to true duals, but that was for power, not sound.

  11. west_coaster Avatar

    I have a '65 Mustang that my uncle puchased new. It was my aunt's daily driver for 15 years, then semi-retired and used sparingly on weekends. He finaly decided to let it go about 15 years ago, and I was given first chance at it.
    From the time the car was almost new and all through his ownership of it, the car had dual exhuasts with old-school glasspack mufflers. When I was a kid it seemed really exotic to me with that deep sound. But when I bought the car, it needed new mufflers as they had some pinholes in them Wanting to keep it "just like he did" I put on brand new glasspacks, but realized after awhile that I really didn't like the way they sounded — too "Impala lowrider" compared to other systems. I ended up replacing them with Walker turbo mufflers (those crackly-sounding Flowmasters have become a played-out cliche in the classic car world, IMHO).
    The Mustang now sounds much more agreeable to my ears.

  12. acarr260 Avatar

    I believe in true dual exhausts (straight pipes) on my pickup trucks. A muffler was an extra $50… and not required in my state. I have, however, been pulled over for noise ordinance violation (but he let me go).

    1. OA5599 Avatar

      My 69 Corvette had dual mufflers, but was loud enough to attract police attention.
      A previous owner of my Syclone ditched the twin mufflers in favor of a single, larger, straight pipe, but was quiet enough that I never got hassled over it. Of course, the turbo sucked up some noise. The Typhoon has a Borla muffler, and it's louder than the Syclone.

    My Sunbeam Alpine came with a cast-iron exhaust manifold (from a later Alpine) and a rotting, kludged-together exhaust system. It sounded pretty good to me. Then I sprang for a nice header and a new exhaust system– a stock reproduction, in stainless steel. It sounded pretty good, too, but it was quiet enough that from the cockpit it was drowned out by the out-of-adjustment tappets and the intake noise from the carb. I was discussing this with my buddy Mitch, who owns a muffler shop. He just happened to have a piece of scrap stainless tubing sitting around, so he took off the second stock muffler and popped the straight pipe on.
    Oh, momma… At idle, the humble 1600cc motor purrs like a kitten. Leaving stoplights, it growls. Floor it and it yells, LOUD, with a nice cough as you lift off the throttle to shift up. Yes, it drones on the freeway, and yes, it's kind of annoying for the people around it. But on the kind of roads that the car likes, it sounds awesome.

    My father still has the 66 Mustang k code he bought new. Shortly after purchase, he bout three complete exhaust systems for it. he used the first two and still has the third hanging in the garage. We're a stock type family.

  18. LTDScott Avatar

    On a related note, I want some opinions on exhaust from my fellow hoons. Originally, my car came with a single exhaust that had dual tips on the driver's side like this:
    <img src="http://img.photobucket.com/albums/v24/iworkoncars/1985%20LTD%20Mine/DSCN0263.jpg&quot; width=500>
    Considering my car is making well over twice the factory power, I converted to true dual exhaust with a catted H-pipe, two mufflers, and a tip on each side a la Mustang:
    <img src="http://www.ltdlx.org/albums/exhaust/DSCN3498.sized.jpg&quot; width=500>
    This was a challenge as the fuel tank is offset to the passenger side since it was not intended to have duals. It required some creative bends to clear the gas tank. Since then I have added a panhard bar for the rear axle, which cut down on exhaust room even more, and required some funky and non-ideal bends to get the tail pipe through.
    I really love the look symmetrical tail pipes, but I'm considering getting the exhaust redone so that both pipes come out the driver's side like original. There's plenty of room on the driver's side, so this would make the bends a lot nicer and give me some much needed clearance. What do you think?

    1. Texan_Idiot25 Avatar

      Bumper cut-outs with dual exhaust (Even half way like the current Rams). Do et.

      Side outlets in front of the rear tires.

      1. buzzboy7 Avatar


      2. LTDScott Avatar

        Not possible because I have subframe connectors which cut down on ground clearance, and the fuel filter is right in front of the tire as well.

        1. TX_Stig Avatar

          It's probably more work than it would be worth just to maintain the true duals, but would fitting a mustang gas tank work? Just an idea. I have never seen the underside of and LTD like yours, anyway, so I don't know what it looks like under there.

          1. LTDScott Avatar

            Nope, the trunk floor is completely different.

          2. TX_Stig Avatar

            Oh well. Then in that case, for the sake of flow I would return to the original routing, just with a little larger diameter outlets and a mild slash cut to them.

          3. Alff Avatar

            Time to go to a fuel cell in the trunk.

    3. JeepyJayhawk Avatar

      Stacks coming out the hood ala-demo derby?
      I kid, I kid… Is there a way to run the duals in the same line (so two pipes side by side) all the way to the back, then spilt behind the bumper and drop out in symmetrical duals? Would this f up your balance?

    4. P161911 Avatar

      Side pipes coming out the front fenders and running just below the door ala Corvette Sting Ray.
      Or run up into the trunk and then out the side at about gas door level (window level on a lowered Civic). Nothing gets a guy with a thumping stereo to raise his windows faster than a face full of slightly rich V-8 exhaust.

    5. Smells_Homeless Avatar

      I'd definitely go with twin pipes on the driver's side. It makes a more pleasing sound to me for some reason. Also, I'm biased because one of my brother's cars is an 80 Cougar XR7 with the same setup.

    6. muthalovin Avatar

      While the side outlets would be totally radical, I think the best solution would be what you have in mind.
      My dad recently got a 5.0 Mustang (90's). It is pretty bad repair, but runs good. He is thinking of doing something like rat-muscle, where he lives all the bondo spots on there, and just let it have a terrible appearance, and just make it a fast beater that no one would expect. Anyway, this is related because he put on a Magnaflow exhaust, and left the stock tips on. One is bent sideways and the other is bent up. I like that look. For comedy.

  19. muthalovin Avatar

    I do like the authoritative sound, just not fart-cans. My F-150 is a V6, and has 2.5" Flowmasters, and sounds damn cool, if I do say so myself.
    The Ducati, on the other hand, has high-mount pipes and sounds like all hell. I remember starting it up for the first time in the carport this year, and the duplex neighbor came running out to see what the commotion was. I prefer to frighten young children with exhaust notes.

  20. Froggmann_ Avatar

    Yes It matters a lot to me. Both of my functioning vehicles have modified exhaust to both increase their performance and sound. As it stands my Bronco has a 2-chamber Flowmaster and 3" piping which result in a nice low toned note at idle and a steady burble at speed. It's not the loudest system out there but it has been known to set off a car alarm or two. On the max (Maxima) I have a Greddy EVO II exhaust that give the car a nice tuned sound similar to the sportier line of Nissans like the G35, 350Z etc. While it's never going to set off any car alarms it does release a nice mellow note that I absolutely love.

  21. Feds_II Avatar

    To me, it's less about the muffler and more about the compression ratio. Stock motors with loud exhausts sound flat (and flatulent). Plus, there is nothing worse than a hearing a car step on it, then take way-too-long to get through the rev range.
    Hop up the rest of the motor so that exhaust note is crisp and whip-crack-quick, rather than flat and bench-grinder sluggish.

  22. Texan_Idiot25 Avatar

    I love a proper V8 tone. Something that's deep and almost subtle at idle, and that growls as it gets louder. I personally cannot fucking stand Flowmasters (F-Bomb needed for my hatred), they are an abomination. All of their noise is WOMMMMMMMMMMMMMMMMMMMMMM resonance, and at idle they sound like popcorn popping in empty cans.
    Tone and sound characteristics are more important to me than outright volume.
    The CST10 is my most favorite, and it really has to be heard in person. It has that old-school rumble down-pat. If you keep it just right at 800 rpm it will vibrate alarms into submission, but it rarely cruises at that range so resonance is no issue. ALL of it's noise comes out the tail pipe, not the muffler body (resonance). Putting around it's enough to get noticed, but not dickishly loud. But, when those secondaries open up… BWAAAAAAAAAAHAHHAHAHAHAHAHAHAHAHAHAHAHA
    [youtube hB_rGuV56mA http://www.youtube.com/watch?v=hB_rGuV56mA youtube]
    It has the great trait of being (by normal people's standards) very loud at WOT, but quiet enough at low speeds that it'll get away with shenanigans. There's been a few times where I've opened it up, only to round a corner at a normal speed to a cop hauling out of a hiding spot. I wave, and continue on my way!
    Subtlety pays off often enough.
    The Formula is probably my 2nd favorite of the cars I have owned. Sounds great in the mid-high range inside, with out resonating your teeth out at 1700 at 80 mph. It's probably not a stock exhaust…
    [youtube wAIr-exOwfQ http://www.youtube.com/watch?v=wAIr-exOwfQ youtube]
    Not super loud (again, loud for normal people inside), but tone is more important.

    As an aesthetic thing, I love a good exhaust note. The subdued gear whine of an older Ninja layed over the thoaty tenor of its exhaust, or the Paul-Bunyan's-Own-Chainsaw wail of a Mazda rotary through a race muffler. From a practical point of view, though, all I ask is that it's loud enough that I know when to shift and quiet enough to be comfortable on a road trip.

    Whenever I have an idiot on a harley behind me at a light revving it up every 5 seconds to make sure everyone is looking at him, I really wish my car was fitted with either antilag or an ignition-cut rev limiter. That way, when he revs it up, I could also rev up mine, and shoot fireballs out the back a few feet in front of him.
    V-Twins can sound good. Not sure what buell does, but the buells I've heard have sounded very nice with a performance tone, unlike the harley that uses the same engine and is running no mufflers. If you keep the mufflers on that harley, it sounds nice. Straight piped? They sound like complete ass as all the noise just echoes and blends together into a cacaphony of awful. The fact that harley's tend to be pretty slow (very slow by bike standards) just makes it worse, as it takes longer for it to be away from you with that noise.
    It kills me that I got pulled over for my STOCK EXHAUST THAT DOESN'T LEAK, and a loud harley went by the the cop didn't bat an eye. He said my exhaust was "shiny and looked illegal" (the car was just washed, and it has a factory stainless tip). So whisper quiet honda accord with a teenage male driving? Pull that kid over immediately. 105db harley with an orthodontist who dressed up in leathers and wants to look hard on it? Lets not bother him even though we could actually write him multiple citations.

      All you need to do is add a small fuel injector and a spark plug to the back of your exhaust if you want fire balls. Have these wired to a little switch on the dash.

    The Challenger R/T 6-speed has a unique factory exhaust compared to the automatic, and it's not too shabby-sounding.

    Laying out diesel engine exhaust & aftertreatment systems is part of my day job, so I have what might be unusual views about exhaust modifications. For example I really have a dim view of the guys who think their 3/4-ton diesel needs to be coating everything for 3 blocks behind in a cloud of particulate matter to add insult to the injury of shattered eardrums; leave the damn DPF (and DOC, and SCR or lean-NOx-trap catalyst where applicable) on there. Driving on the street is not a tractor pull event, and you're doing more harm than good toward the general population's acceptance of diesel engines (where most folks impression of a diesel is fueled entirely by the smoky, sluggish pieces of crap that GM foisted upon us 30 years ago.

    I agree completely. In fact, I took the drag pipes off my VTX and replaced them with the stock system because the volume from the drags was cramping my style. I really like to twist on it, but I'm a mostly socially-responsible person. Well, when not being socially-responsible stands a good chance of earning a roadside interview anyway.

    I wouldn't mind unusually loud cars or bikes as much if the owners had more restraint. But I have very little use for the folks that have to straight-pipe their Harley and then blip the throttle every 30 seconds for half an hour until the engine is ready to turn into a puddle of molten ironprovide throttle response. Or the people that (in winter) feel compelled to leave a loud truck idling right beside the apartment building at 11 PM for an hour (never mind that the engine would have retained some heat over that short of a time period.)

    When it comes to cars, loud is not always better.

    I was in the market for a 2011 Mustang V6, but after driving it I wasn't impressed with the tune. It sounded as good as any V6 this side if a 370Z but my Mustang has to have that rumble. So I bought a used GT.
    And installed Bullitt mufflers.
    So, yes… "important".
    (And I'd sell a KIDNEY to have a Boss 302 with a RED key).

      Yay! I have video! Try this with a V6 soundtrack.

    They are EVERYWHERE down here in KY. It's easier to count the trucks that don't have them. Hell, I even saw a '90s S-10 with dual stacks…but only one was connected to the exhaust.

      If the other was a snorkel attached to the intake, that's still forgivable.

    Call me a simpleton but I absolutely adore the sound of the flat four coming from the wife's stock Impreza.
    I've been toiling with the idea of duals on my F150 with an intake but don't want to mess up my ECU tune.

      10 years ago I tracked my Impreza RS with the 2.5 NA engine and a CAI. A pal said that was the sweetest sounding car he ever heard. I was wringing it out too… it did sound good.

    It has got to be loud enough for attention but not so loud to be obnoxious. So very important.[youtube Mo-cTXFtfN0 http://www.youtube.com/watch?v=Mo-cTXFtfN0 youtube]

    I would love to make my car sound like one of those diesel LMP1 cars. Awesome diesel sounds inside the cockpit with just whooshes for those outside. Of course, adding at least two more cylinders and a turbo isn't in the budget right now so my only exhaust goal is to make it less deafening on the highway.

      Ah poopy, embed blocked. Well, in summation, Flat-6 is awesome.

    i love my truck's nearly stock exhaust note. Only has aftermarket headers on it, but it burbles nice at idle, and really wakes up at about 2k RPM I'm saving up for true duals with electronic cutouts right now.

  43. Spencedaddy Avatar

    No mufflers on an otherwise stock 93 Lightning with side exit? yes please! thats my setup!
    real nice and deep at idle…..gets LOUD at WOT, and perfect for getting into people's windows
    sets off alarms too….its like a hobby of mine

    There has never been a vehicle in my driveway that did not have it's exhaust modified. Be it a hacksaw and a glass-pack or a full custom stainless system (with dual glass-packs ) I've gotta hear the exhaust.
    <img src="http://www.jegs.com/images/photos/200/289/289-24241.jpg&quot; />
    I've grown up since the days when my exhaust consisted of just Super-Competition headers and a 45deg elbow with Cherry-Bombs exiting under the door, and no longer like loud obnoxious sounds, but I still love me some glass-packs. I keep several laying around just in case a stray car shows up.
    We just redid the exhaust on my lemons car using, you guessed it, a glass-pack. I could listen to this all day…
