when i bought my '00 gsr, it had jdm itr headers on it already w/ stock piping. I dunno what he did, but now the cat converter cracked off (non-repairable). I'm looking for a direct bolt-on fitment.

Would I need to get the jdm itr cat converter in order to fit my stock b-piping, since i got the jdm itr headers??

need a response asap.

 

you will need the longer USDM length cat...

only the 94-99 GSR had the longer bpipe requiring a shorter JDM length cat

 

isn't the jdm itr headers have a 2.5" collector though? when u say usdm, do u mean usdm itr cat converter? or???

Could i just get a cheap ebay one that is made for my car then?

i thought the jdm headers extend a lil' longer than the stock?
