Carsound makes a few different sizes for hondas, from 2" to 3" i think. Most ITR guys run 2.5" carsounds or slightly modified ones from SMSP.

is the 2.5 a direct bolt or you need to modify it a bit? also where can i get a carsound cat. i'm in so cal. thanks for the info.

A 2.5" cat only bolts directly onto a header with a 2.5" collector (JDM-spec header) and a 2.5" catback. The ITR uses 2" piping all around but I have no clue what a GSR uses.

isn't usdm ITR 2¼ piping front to back? and can you get a car sound Cat that hooks to JDM header AND hooks to a USDM Catback

Yeah, but you'd have to order one from Carsound with different diameter inlet and outlet.

Actually, you're right almost. The header is 2" and the catback is 2 1/4"... one of you guys correct me if I'm wrong

just check with Mike at http://www.ipsracing.com or Dave at smsproduct@earthlink.com

They can both make custom length cats.

GSR cat is 5" shorter than the ITR, LS, GS, & RS,

Trust me, Whatever you do DO NOT buy a Comptech cat.

First they'll send you a GSR Cat, then they'll double charge your credit card to send you the RIGHT one, and then about 5000 mi. after you put it on, the screens crystalize and cause restriction. Too Bad your in Cali.
I'd sell you my "GUTTED" Comptech, but it wont pass the sniffer test, or whatever it is you call it...

GSR is only different from 1994-1999. 2000 and 2001 is the SAME length

Yep,

Not sure if they changed to standardize parts por what but 2000 and 2001 went to the same length as all the others.

they've all been pre-99
