On a standard wrx system you will have a cat in the up pipe, the down pipe is in 2 sections with a cat in each, the centre pipe has a resonator chamber to keep the noise levels down and then a backbox at the rear. The usual upgrade if you want to keep the cats in place is to replace the 2 piece downpipe for a 1 piece sports cat downpipe. The centre pipe and backbox are interchangeable as long as you stay with the same size 2.5" bore of course.
Where should the cats be on my car?
