s14 high flow cat

[kouki_s14]

as most of you guys know i recently swapped in a RB and the gas smell is finally getting to me. i hoping a cat will help with the smell. i searched around and even went to a exhaust place. the exhaust place says its hard to find a cat so small.
for the s14 guys you guys will know what im saying, our cat is right after the headers on the KA, obviously i dont have that anymore and i was looking around for a cat to fit where my dummy cat goes. all the ones i've found seem to be a little too long compared to the dummy cat. i'd rather not cut my exhaust piping or downpipe and have to reweld flanges and such. if possible i want to buy one i can install myself.
so have any of you S14 guys found a cat to bolt right up to where the dummy cat fits?
all the one's ive seen are for 240's (s13's and s14's) but never specified anything about a dummy cat


thanks for any help
