No it wont bolt up. You will need to do a custom axel back w/ aftermarket cat.

Is it the true JDM ITR 4-1 or is it a DC Sports or knock-off? The length will be fine, so no problems there. The only concern you will have is the true JDM 4-1 has a 2.5" collector which won't match up to the cat properly. You don't necessarily need a new cat but the flange will need modded by an exhaust shop. It would probably be easier to just get another cat though.

yes they are the true jdm 98 spec itr headers.....so it wont bolt onto my stock cat?

I think that http://www.landspeedracing.com makes a direct fit cat for a JDM Type-R header to USDM style exhaust.
