When doing a swap (EG civic and type R or SIR) and installing a 2 1/2 or 2 1/4 exuast, the cats intake and exaust ports are both too small for the flanges for the headers and the exaust system....what do you guys that swap do to solve this?
get ones that fit mig welded on in place of the old ones! If im not mistaken camo tuning does this kind of job quite well! You should check out there site im pretty sure they got info on it there!
