What in your opinions is the deepest loudest exhaust to be put on an LS1? From my searchings it would be this combo:
-a proven Longtube Header (Kooks)
-an H-pipe (True duals for volume and sound, deep muscle car sounding H over an x pipe that has higher flow and higher pitch)
-3" exhaust pipes (wider pipes=bassier/deeper exhaust)
-dumped/turndowns at axle (LOUD, louder than extra pipes bent under or above the axle)
-Hi-flow cats (loud sound, but cats are necessary to kill rasp/higher pitched clicky sound)
-Straight Thru Bullett mufflers (seem to be the obvious and popular choice for loudest sound and deepest sound)

Opinions and comments are suggested. I want as much response as I can to this post because I am looking at having a custom exhaust done in a couple weeks and need to have the plans laid out. Thanks in advance.

Lose the cats.
With true duals you don't get any rasp...

I just put on texas speed's true duals with dynomax bullets today. They are backed up by my LPP headers. They are one of the deepest exhausts I have ever heard. At least at idle. There comes a point where you start to sound like a truck though. Id say 3 inch straights is deeper yet but it sounds like a dump truck. Just my 2 cents sir.

im runnin QTP lts, o/r H, and dynomax bullets

they sound great at WOT, very deep at idle and worth the money.

Them dynomax bullets are really deep & basey. Glad to see im not the only cam only 'camaro running an aftermarket rear.

blown03mustang

I am going to vote for a full hooker exhaust. I say this because I have hooker headers, the ory, and am doing a custom 3" cb with a hooker aerochamber muffler and some hooker tips, not installed, but I love the way they sound. It's supposed to be pretty tame at idle, but when you open it up, it gets deep and mean. I have heard on e in in real life, and it was nice. That's why I chose mine. If you want it to be loud, just get a cutout.

BTW, blown03mustang, I love the way that car sounds. IMO, it is one of the best sounding f-bodies I have ever heard.

Blown03mustang, BTW, if you don't mind me asking, what are the specs on that cam?

blown03mustang

thanx, it definitely has very unique sound to it. i still cant believe it only cost me half the price of the TSP td's

I'm hoping mine will sound good with the torquer v.2 cam that I am planning on getting and I am debating gettin an electric cutout.

blown03mustang

thats the cam im running

So with no cats I won't have rasp? Almost everywhere I read, people with dumped true duals have rasp above 2500rpms~ with straight thru mufflers whether they say it or not I see it in videos too. Not at WOT, but cruising and slight punching (and this only occurs on non-cammed cars). More opinions on this please, I know no cats=more hp but I am looking strictly for sound.

blown03mustang

my TDs have no rasp whatsoever and none of the ls1's with duals ive ever heard have had rasp. ditch the cats and stick with the straight thru mufflers

Z28MaroJoe

But you have a cam. Like I stated, cammed true dual cars have no rasp. I need some opinions from bolt-on true dual cars and I need to check more sound videos.

blown03mustang

cams normally makes the exhaust "raspier".

Mods to the engine change the exhaust tone, but TD's are the loudest. SLP Loudmouth after that is loud.

depends on your mufflers. if you have a fiberglass packed muffler with an X, you won't see much rasp. If you have a chambered design like a Flowmaster, your gonna see rasp with no cats. Personally, I'm pulling the X to put in an H on mine purely for better sound...

Bolt-on car checking in and I just got my TSP duals with the Moroso Spiral Flows on and love them, real deep loud and mean sounding. Probably the quietest of the three mufflers they offer though. I have never heard any car with true duals have any rasp at all at any rpm. Now if you are talking about interior resonance that is another story but I dont see cats helping that. After having duals though I will go no other way!

Flowmaster+no cats=Sounds Like ***!!!! I had a flowmaster with no cats on the stock y, sounded like **** IMO. Go with the tsp true duals with some hooker headers, I would. I haven't heard of any of the the tsp true dual cars having rasp.
