View Full Version : Your sound...what is it?

Let’s face it. Sound is subjective. Everyone has an opinion when it comes to exhaust (http://bit.ly/2csjVFe) and how they would like their vehicle to sound.There is no right or wrong answer. So, what is your sound? Are you committed to ear-splitting volume or do you like to hold a conversation inside of the car? What was the first modification that you made to your exhaust system? Are you happy with your current setup or do you plan on making a few changes in the future? Header-back, Cat-back, Axle-back or muffler swap? Voice it all here.

I guess if I had to explain it, nowadays i'm into something that sounds good and kind of noticeable at idle, low drone on cruising and sounds bitchin at WOT.

I was a religious 2 chamber flowmaster user for years, at one point in time I owned four cars at once all with 2 chamber flowmaster mufflers.

Last exhaust system I used spintech mufflers in what was the db equivalent to a two chamber flowmaster, got tons of compliments. I think that type of muffler would be on the loud side for my current taste.

Really dig the sound of the Stainless steel works mufflers Stielow has been using and i'm intrigued by the black widow mufflers but pretty sure those are going to be too loud for my current taste.

hope this answers your question.

I like a 60's era muscle car rumble such as a Ram Air IV Pontiac GTO, authoritive, low drone and violent when hammered down. I am currently building a car with a modern LS1 (motor will remain stock (2004 GTO) and putting it in a 69 Pontiac Firebird convertible. I am currently in need of exhaust for this build so your post is timely. I want to stay with a transverse muffler tucked up nicely between the mini tubs. I do not want something that is too loud to hold a conversation in the cabin of the car and absolutely do not want any annoying drone. I had to go with tubular headers, I prefered the factory cast iron manifolds that resembled cast iron headers of the 60's but clearance was an issue so I purchased Holley Black Heart mid length LS conversion headers in stainless. If you have any reccomendations I would appreciate it. Thank You.

This one since 1991, the Flowmaster transverse mounted duel inlet dual outlet muffler kit, updated with 2.5" mandrel tube turn down tail pipes a Scavenger D-Port. :D

The first modification I made after the system was installed in '91 was a radio delete. :unibrow:

That sound to me is exactly what I am looking for, nice rumble but you can tell smiles are just a gentle push of the go pedal away. Any drone associated with this system at highway speeds ? Thank You for posting the sound link.

No much drone, it will get a little 'bassie' around 16-1800 rpm under load around town but at highway cruise it's in the 18-2200 range with the close ratio 6 speed and 3:73's. Floor of the car is Dynamatted and the rear seat back has wool commercial carpet padding in it.

Motor is a 355 SBC with AFR heads, low 9.5-10 compression and Doug's headers w/ 1.75" tubes.

This gives a decent idea of the sound range, aggressive throttle at 2:05.

Thank you once again. She really means business when you turn up the wick, sounds real aggressive. Do you think the modern GTO stock LS1 would sound similar with mid length Holley Blackheart headers.

As much as I like the LS platform, they'll never sound like an old SBC. :D

Exhaust notes deal with so many variables, just changing my tailpipes made a major difference in sound from the original Flowmaster Z/28 style tailpipes.

Im running the Flowmaster Super 44 now and really like the nice low grumble I get from it. I do get a lot of highway drone at 2000 RPM though. To fix this, I thought of moving the mufflers to an axle back muffler setup and instead of the tailpipes pointing down at an angle, just having them point straight out the rear with exhaust tips. This will bring the volume up to the rear and hopefully help with the in cabin drone.

Recently, I watched a video clip of the Mustang GT350R. That exhaust sound is wicked. I'd like to keep my Flowmaster rumble while cruising and somehow get that sharp raspy scream of the GT350R at WOT. Any ideas?

Something we can agree on Sieg. :RunninDog:

Super 44s (http://bit.ly/1G5HbwC) are aggressive mufflers, but there are some things that you can do to tune your sound depending on how your system is currently setup. Are you running an H-Pipe? How much tailpipe are you running after your mufflers? If you have a second, give us a call at (707) 544-4761 and we can discuss some of the options that will help you find the sound that you are looking for.

Before turbos I always had Fowmasters and LOVED the sound. The last time with them was with a homemade X pipe/expansion chamber and dumped at the rear. The thing sounded like an animal! It added 100+ HP at the ear without a doubt!!:mock: LoL! If any of y'all were on the PT in 2000 or so and saw it throw parts on the dyno at Comp, then you can attest!

I tried with the flows for a year or so with the turbos, but it didn't sound right and ended up changing them for some straight thru Dynomax bullets. After we built the TQ arm setup, I had to go with single 4" exhaust and ended up getting a Magnaflow and really like the way it sounds. Nowhere near as good as a high compression engine with flows, but still pretty good tone and volume.

So me personally, I like to hear a deep rumble with little resonance and not obnoxiously loud at WoT.

This is the best video I have with the current exhaust.

My 89 C4 has a Lingenfelter SBC 427 with TPIS Long tube headers into a "Y" into a single 3 1/2", into. "Y" and to two Delta 50s at the rear bumper. I love the sound but, the single 3 1/2" and the two mufflers weighs 43 pounds. I am thinking about putting a 24" Slim Line with 3 1/2" in/out with a 4 1/2" diameter up to the front "Y" and dumping/angling down the exit in order. I hope the sound doesn't exceed 100 dB at 50'.

I should be able to save a lot of weight with a Slim Line muffler.

Stuck with 2.5" on the LS6. Magnaflow exhaust. I like the attenuated rumble.. even better are the cutouts.. which I can open a little,... or a lot and really hear the rumble. Don't get me wrong tho.. the magnaflows definitely wake up when you get the rpm's revvn'.

Exhaust Cut Outs make it nice to have that option of scaring your neighbor and unleash the beast within', then quietly cruise on and enjoy hands free unit to take a phone call.

deep rumble that you can "feel" at idle and cruising and screaming at WOT

So i will try to research this after asking actually but good for conversation. We can all agree that an LS motor can sound horrible sometimes but dangit if C6 corvettes don't typically make the most beautiful sounds out there. but why is that exactly?

I have been hotrodding since the early 70s so I prefer the old school sound. But I find as I get older I like a bit less noise so I can talk while I want to get peoples attention with the loud pedal. I prefer the sound of the Flowmasters over the Magnaflows, they just sound right. I'm currently running 3" exhaust front to rear and started with 40 series but later changed to 50 series mufflers. I have considered adding an H or X pipe, but I don't like how they change the sound. This is an older pic when I still was running my old ST10 four speed but the exhaust is essentially the same except for 50 series mufflers and longer turn downs now.
