I want to run my buddy's jdm type r headers on my gsr... so i know i need a type r cat... but i need to know will it clear the oil pan and so forth and when i bolt up my exhaust which is a greddy exhaust for gsr will it bolt up to the back flange that comes off the cat or is the flange too big... and i need to know where to get a good cat from not too expensive and not too cheap...


thanks Manny

 

an OE jdm cat is what you need. call steve at hmotorsonline and see if he has any left

 

It will clear, jdm itr is 2.5 I believe, so the cat has to be 2.5 as well. The Greddy should bolt right up, my stock one did.

 

You should have no problems with a jdm itr cat. It has a 2.5 inch inlet, good for the 2.5 inch collector from the header, and the outlet of the cat is 2.25 which should bolt up to a greddy exhaust.

 

cool thanks for the advice fellas

 

what? i thought the jdm itr cat is 2.5 both ends? why did honda make it like that cuz wont that bottle neck the flow? which is bad right?

 

you will have no problems
