98 ITR.

Ordered the JDM ITR 2.5" header. What additional will I need to order to make this work and bolt up? (Everything else is stock). I know it probably won't bolt-up to the stock cat, what should I buy that worked for you and where do I get it ?

Also looking for an APEX-i N1 muffler with piping that will bolt up to this. Thanks.

 

You need a 2.5" in/out cat or test pipe, a 2.5" donut gasket, and modified b-pipe to mount it up.

SMSP offers a ready-made cat, and a piece to remove the bottleneck in a stock ITR b-pipe.

 

I have the exact setup you need.

Shamelss plug ( I know) but I gotta sell it...


As Pat said, SMSP will fill your needs.

 

Keep in mind that the new cat you'll need will have to be 1" shorter than the stock ITR cat since the JDM header has a long collector.

 

Who uses cats ?

i do. it's safe for the environment.

 

dont forget, when u order the cat from smsp get the obd2 version(20 bucks more) unless you are switching to a obd1 system ie hondata.

 

Thanks for all the replies.

Someone shoot me a link or a phone number for smsp or whereever I can obtain these parts. Thanks.

Staying vaguely on-topic, why have cats gone up so much in price? When I put my JDM header on, I ordered a universal 2.5" cat from Jeg's for a little over $50. Same thing now is over $150...

Similar price change in Carsound cats?

 

Does this whole set up still pass Dyno emission inspection in the northeast?

Dunno, I paid $100. for my Carsound through IPS 3 years ago but I think I got a break since I also ordered a header.

 

SMSP is the way to go

 

test pipe **** the tree huggers lol.........

I couldn't pass smog here in Cali with the JDM ITR header + 2.5" carsound + ITR cat-back on my GSR. Once I changed the 2.5" carsound cat to the OEM cat (modified to fit the 2.5" collector on the header), then I finally passed. Just some fyi in case smog is an issue for you.

You'll also need the S2k donut gasket.
