Anyone know what dimentions(length and bends) for a test pipe to replace my cats.I ordered a set of SLP headers w/o the AIR stuff,but don't know if the Y-pipe routes the same way as my stock Y-pipe.I also have a 3" intermediate pipe.

We need Perry Mason

 

The Y pipe is routed the same way. You will need the cat adapter. If it is a single cat the length is 20.5 inches from end to end. I just had a test pipe made for mine and it works great. Better sound and performance.
