FYI...
This is a 200 cell count stainless wound cat and the inlet is 2.5" to mate to factory manifolds or shorty headers. Just information I had to call around to get that everyone always asks.
I also made 19rwhp and you can make over 600rwhp with these mid-pipes.
This is how far you can go with shorty headers and 2.5" JBA mids.
