I just installed long tubes on my car, and the TSP ORY but im not really diggin the whole set up with that and the loudmouth... I know no cats tend to be somewhat raspy but what exhausts sound good or decent with Lts and an ORY?

-thanks

First thing that I was going to say was stay away from the raspmouth but looks like you already figured out that its sound is sub-par. The Borla, Corsa, & GMMG are some great exhaustsw but are a bit pricey. If you already have the LM you should just put a muffler into the I pipe, such as a dynomax or borla which will quiet it down a bit and cut the rasp out of it. I'd recommend that you loose the slp muffler and put a 3" sweet thunder in the I pipe and then straight pipes out the back.

A Hooker or SLP dual/dual would sound great (rasp free), the dual/dual will be the quieter of the two.

Or as suggested above, if you want to keep the current system you could swap out the SLP resonator for a muffler, but that will still be louder than Hooker or dual/dual. You could also put a couple race bullets in the ORY where the cats would usually go to further take the edge off.

Question is, do you just want to cure the rasp, or do you want a quieter system?

since you already have the LM the just get the LMII muffler. I had it with lt's and ory and liked it. fairly deep and was loud but overall whad a nice throaty tone.

I have the Borla with hooker LT's and ORY its loud but not raspy and sounds real clean and crisp when I get on it. Send me your E-mail address and I'll send you a clip of me getting on it.

i vote for Hooker with LT's and ory! thats what I'm about to put om as soon as i get my hooker in the mail! I heard nothing GOOD things about it. Its kinda quite at idle and cruise...just a mellow rumble and its like loud mouth loud(with stock cats and manifolds)at WOT! sounds killer

the best way to keep it loud and not be raspy is to not have an ls1

I really doubt it's the motor that makes rasp. Seen
many people claiming gutted cats on stock exhaust
makes rasp; mine didn't. Seen people say a Jet Hot
Y-pipe will rasp, if you leave the cats out. Mine
doesn't.

Why? Look inside the stock cats, look inside the
Y merge of the ORY. Sharp edges in the airstream
is what makes your rasp. Like a grass harp. I took
3/8" of stick-in out of my Jet-Hot Y before I put it
on. On my gutted cats I dressed every sharp edge
in the pipes with the carbide burr. No rasp, just
mellow.

I have a TSP ORY also, I was planning to use that
but found the used Jet-Hot Y to match the headers.
The Y merge on those was just as bad, the "little"
pipe sticks in past the "big" pipe wall by about 3/8".
It's just a bit of manufacturing slop (better sticking
into the pipe, than a gap, I guess) that you can
improve upon (flow, and sound) with a little time and
power tools. The TSP at least is easy to work in; the
Jet-Hot is more bent and hard to reach all of the
sharp edges. I had to use a flex-shaft tool stuck
down a piece of shop-vac extension.
