So I want to use SZ 3" down pipes and test pipes. I was also looking at Z1's newly offered PG cat back, which seems to be simply straight pipes. So my question is: what makes it worth the $600 they are asking vs welding up my own 3" cat back system? I'm confident I could, and it would be way way cheaper. Input?
