How far can you stretch stainless pipe ?
How far can I stretch say a 3" or a 2.5" Stainless pipe ?
I"m collecting the parts for my header install. The problem is my headers have a 3" collector and my exhaust/cats are 2.5".
I cant decide whether to buy some 3" stainless pipe and then try to stretch my h-Pipe to fit it. Or buy some 2.5 and try to stretch it to go over the headers.
What do you think guys ?

With an LS1 you need 3" inlet/outlet CATS else they will be too restrictive. Also you don't want to mount the CATS directly to the headers, you need a bit of space between them. You can by neck down pipes to go from 3" to 2.5" (not sure where but I've seen them, might have been Summit).

2.5" was what the entire stock exhaust, including cats was made from. When I upgraded to high flow cats..i had to get the right size.
