need some help guys.... im planning on ordering a high flow cat as i speak. for the 2000 gsr. And i did not get a chance to test fit my jdm itr header. so i dont know exactly how much longer is the JDM itr header. is when compared to my dc 421 header.
question is this... i dont want to buy a universal cat.... and upon install, the cat is too long... so for all you ppl who has it. you advise if deeply appreiciated

is there a site where i can buy a PRE-MADE cat that would fit my application?

btw this is my setup- jdm itr header->highflow cat->apexi B-pipe

?

 

i know there might have to be modification one reason because the jdm ITR header has a different O-ring then any USDM one. Correct me if im wrong.

 

yes the opening on the most jdm headers are 2.5 in diameter... therefore you must use a 2.5 inch donut.
my ? is what's the length for testpipe/cat you guys are using for the itr header.
or is there a site where i can buy the cat. converter pre made?

 

Dave, H-T user "SMSP" can custom make a cat for your setup

 

thanks i IMed him
