help with exhaust
How much back pressure does tha LS1 need to run right? I am going to be running stock C5 manifolds, no cats and 2.5 inch dual chambered exhaust to the stock square tips.

Re: help with exhaust (70 LS1)
Can you get away with "no cats" in WA? They check here in AZ if you live in one of the large metro areas. I don't know about the C5, but I ran with a cat and straight pipe set-up on my C4 and it worked great;, the cat provided the needed back pressure. :)
