i need the gasket ring that goes between downpipe and CAT and i have the 96 jdm ITR CAT. no one seems to have it and i was told i have to order it from japan... is this right?? does anyone here know where i can get one the one i have is leaking bad because its broke in half and nasty.... any help guys???

 

have you checked with the local acrura dealership for a US ITR gasket ring?

 

no i failed to do that. i just checked with every sinlge muffler shop here. i didnt check acura because i thought that the jdm ITR downpipe and CAT were larger in diameter than the usdm version. is that tru or am i wrong???? do u think the usdm ITR CAT gsaket ring would work??? does anyone know this?

 

oh the reason i chedked wiuth muffler shops was because i thought they would have larger fdiameter gaskets for u know like v8's and other cars u know

 

is it 2 1/2" outlet? if so u would need to order the one for a acura legend. i forget witch year just ask. but i know the legend gasket is also 2 1/2" if thats what your lookin for.

 

yea its 2 1/2 in out let i do beleive its very large.....

 

I believe the inlet of the jdm ITR cat is 2.35"

This is due to the 4-1 header. any ring of that size will fit.

it's not 2.5"

 

no i dont have the 4-1 header that was 98 i beleive.... mine is a 96 jdm ITR header and cat on a 96 jdm ITR b18c.... all i now is the inlet is pretty large and teh gsr one is definately too small for it i am confused as to what to get. i dont want to go around buying all soirts of gaskets from dealerships and they not working and i cant take them back u know

 

ok poison is right the JDM 4-1 Header is a 2.35 collector but it flares out at the end to a 2.5" collector that's why some ppl think it's a 2.5" when it sorta kinda isn't get what I'm saying?

As far as the gasket check out a USDM ITR and go to a honda dealership, you should be able to get it from any 2.5" colector

 

Yea, measure the gasket ring area, I am almost positive it's the 2.35" inlet. And any ring that will go in there will work.

 

ok i will definately try that out thanx guys for the input.....

 

2.5 inch collector is also on the s2000 and you can get a 2.5 inch donut gasket from honda or aftermarket performance shop
i got one..and it was like 20 bucks

 

xchosun1x u have a jdm ITR header with CAT ???? is that the donut that u used for sure?

 

go to autozone and just tell them you want to match up a gasket because its a custom setup and they will bring out the box of gaskets and just find one that fits.
