I've got a B18C in a CRX SI and I'm doing I/H/E.

The header/downpipe combination that I'm getting is fitted for a B18C.

I'm getting exhaust that's fitted for my chasis.

So for the test pipe/free flow CAT/open CAT (whatever you call it), should I look for one that's made to fit a GSR or CRX?

I'm just concerned about one test pipe being longer than the other. Based on pictures it seems like all open CAT's are made the same length, just have dfferent sized inlets/outlets. I'm trying to avoid taking a trip to the muffler shop.

This is what I'm looking at so far:

get one for a crx, and as long as it's the same diameter, it should be gravy.

at least it's worked for me before.

 

what if I keep the stock B18C header/downpipe, should I still use a CRX test pipe w/ the exmag exhaust? Or should I get a GSR testpipe?

 

go with crx, if the diameter of the pipe matches the exhaust.
