I was looking at headers, cat-backs, etc. today and am wondering... why
would you run a 3" header collector, into a 2.5" cat converter, then back
into a 3" muffler? Wouldn't it make more sense to use a 3" cat and run 3"
pipe all the way back? Is it because this mod would kill your low end power
on a 5.2, or is it just an emissions issue?
