Default 3" Exhaust System

I am looking to outfit my Z06 with the lowest restriction system on the market. I would like to get down to 9" of Hg measured at the manifold collector. Any recommendations on a 3" exhaust system rearward of the cats with low restriction mufflers?

Stainless Works is coming out with a 3" cat back system VERY soon.. It comes with a 3" Xpipe as well that runs right from your header collectors back to their custom 3" in and out high flow mufflers.. I heard their prototype system and it sounds killer.. Nice and deep tone without much resonance at all..

This system, along with their long tube headers will be going on my car sometime in the next 2-3 months..

Stainless from front to back in 3" is defintely the way to go in my opinion.

I will post more details when I get them..

Matt, do you think stock cubed LS1s have much to gain from a 3" exhaust?

3 inch is big :eek: Maybe for a 427... The only folks who seem to have any gain here is super big blocks and huge single turbos...

The loss in low end power (and maybe the whole RPM range) would probably not be good.


I'd stay 2.5...
