Your sound...what is it?

[Ron@Flowmaster]

Let’s face it. Sound is subjective. Everyone has an opinion when it comes to exhaust 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.

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

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.

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.
