im having issues on completing my exhaust system. just did a jdm h22a swap in my 92 si. the newer downpipe's flange is bigger than my orginal cat flange. the h22a downpipe measures about 6" from tip of triangle to base. my cat flange that mates to the downpipe measures about 4".
im lookn in ebay with no luck finding a hi flow cat with a 6" flange on downpipe side.
i think i read somewhere the compression on a jdm h22a is 10.6.1 compared to a usdm 10.0.1. is this the reason exhaust between the two differ..?
what can i do or where can i buy a jdm cat or test pipe.? or will i need a whole new exhaust system.?
will this work for me? notice jdm fitment note
