#11303, "Apex'i N1 or GT Spec Downpipe, do they make them with a cat?"
I have searched a couple webpages and all I see are downpipes that go from the turbo housing and replace the cat. RoadRaceEngineering makes a 3" downpipe w/ high flow cat, but I would rather stay with Apex'i if I can. Does the N1 or GT Spec downpipe allow for a high flow cat?

i believe all the Apex'i DP say they are "for race use only" which means they dont' have a cat i guess. but Bucher and ATR are really good from what i've heard.

if you want to fabricate a little, you could buy a no cat version and get a cat and weld it all up. but that depends on what kind of work you want to do to it. also, buschur and atr dont have cat versions i dont believe.

true that. i was going to go with a rre downpipe with an n1 catback. those will bolt together. then i decided i wanted an atr catback, and rre doesnt cater to that with a downpipe so i just got a full atr turbo back.

agreed. I haven't found a better shop yet--plus they're usually the cheapest among actual shops---check them out, they're usually happy to answer questions..
