i have a 2000 ss and i was wondering if anyone would be able to tell me how much hp i would be getting out of kooks LTs kooks X pipe and bassani cats.
thanx

 

with out a tune, you could prolly safely see 20-25 rwhp gain. with a tune prolly closer to if not more than 30 rwhp gain. Doing true duals like that is the way to go, and its hard to do better than kooks as far as headers go! Its noticeable, I know that much!

 

yea the place where im getting everything done at is doing a laptop tune and they dyno it
