so i bought a blox header and now knowing what i have to do to make it work i really dont wanna have to cut or weld anything. I am running a dc header with oem cat with apexi ws full catback which is 2.25 all the way threw. So i am trying to find out is there an exhaust system that will work with the blox header without cutting or welding and using a cat not a test pipe. I am planning to change my whole system to a 2.5 was thinking of the buddyclub spec 2 and a 2.5 cat will this setup work with the header?

 

what size is the collector?
any cat back will get the job done

 

you need a 2.5in cat, either aftermarket or one off an ITR or CTR. then you need an exhaust designed for one of those 2 cars.

BC spec2 and an ITR cat will fit like a glove. the non type R cats are tiny. even the 00 SI uses a little one.

 

are the itr cats short enough to let my blox header fit direct? the blox are hytech replicas too so the length of these headers go all the way pass my header and cat right now.
I have a 99 gsr with dc sport and a oem cat right now.

 

custom lenght cat is what you need

 

get a smsp can 2.5 to 2.25 made to length will bolt right on, or even a carsound high flow cat 2.5 to 2.25 and have them weld it to the exhuast or add a flange easy fix

 

if anyone has a setup of a hytech or blox or anyother sort of header like these. Can yall post up your set up. like a custom exhaust or cat something like that wanna see some pics too.
