SS Exhaust on a v6

has anyone changed their entire exhaust to 2.5 inch all around?

I know ours is 2.25 unti the very end then its 2.5 inch.

Does the increase diameter do anything toward exhaust note? good or bad?

or has anyone done 3 inchs?

I have upgraded my midpipe to one off the LS3, I haven't really noticed much of a difference. If anything it did deepen the exhaust note just a little bit but barely noticeable.

The V6 exhaust is 2.5" from the the engine back to the far end of the H-pipe. Then it drops down to 2.25".

Some members have reported an improvememnt in exhaust note with a switch to the SS system.

A catback take-off from the LS3 SS will bolt right up to any V-6. I doubt there's any real performance improvement unless you're running some kind of forced induction system.

If anyone has one laying around, I'll be willing to give it a try and let you know!

That's correct but it'll be cheaper just to get the whole cat back like I did. Because if you just get the mid pipes that's one more end you'll have to weld. Also another thing to think about is. The piping after our h-pipe is 2.25 the LS3 is 2.5 another difference is that the resonators are bigger.

, same here and then it was about $100 to have the shop switch it with my stock midpipe and weld on my MRT v2.

Yes the MRT will be fine

No you don't need a better catback. Might help but certainly don't need it

If I were you I wouldn't spend money on a name brand catback...exhausts for these cars don't make noticeable gains and wouldn't be worth the money versus the little hp gain... So it boils down to whatever sounds good to YOU....imo if you're getting the turbo setup that automatically eliminates long tubes...so exhaust wise I would get the LS3 cat back and weld the MRT's on

Have you considered looking into a supercharger? With the supercharger, you can keep your headers. Just a thought.

If you aren't getting the turbo soon or don't know if you still might get it, I'd definitely do the headers. If you go turbo, you can probably sell them later. You won't get what you paid for them but you'd be getting something.

That's a good deal, but it's never anyone close enuff to avoid shipping!

At least you're not in Florida, LOL, that's where I see most available!

Anybody in Vegas got some collecting dust in the garage?

SUKXOST, you know people, help me out here...

The turbo kits I saw were remote mount so you would be losing a muffler and have a resonator on the other due to the turbo being mounted in the back.
