will an after market eg si exhaust bolt right up to the jdm 4-1 header???
the cat (or test pipe) is right between the header and the exhaust...

the jdm header is 2.5" so more than likely your cat wont bolt right on. they sell 2.5" flanges for people running 2.5" header collectors, blox makes them, and probably others as well.
