Help with test pipe
I recently purchased an HKS downpipe and an AMS catback, which uses the stock cat. Does anyone know of a testpipe that will bolt the two together? I know that the HKS pipe is Alittle smaller than the catback.
I just took mine off and would work fine for you as the flanges are the same size as stock cat...

There is no test pipe that will mate the two. I just went through a similar experience. You either need to custom fab a test pipe (which I did), or go full AMS from the dp to the exhaust tip. AMS uses three bolt flanges when everyone else uses two bolt flanges (or slip flanges like Buschur). In addition to the three bolt flanges AMS uses, the flanges aren't even in the stock locations.
