Hey, I was wondering which downpipe is best for my 06? I have a Apexi N1 Catback which tapers to 2.5 inches and fits my stock downpipe perfect. I am getting a catted down to prevent the problem w/ the 2.5L engine.
I can't decide which is best...the Invidia w/cat for 550, the Helix for 425, or the Cobb for allmost 600. The one I'm looking at now is the Cobb because it states that it will fit to the stock Cat-back and that means that It will fit my Apexi, unless the other two also fits the Apexi.
My plan is to do a TBE that prevents boost creep for now, and get the accessport later because Stage-1 power increase is very minimal, I know the torque and hp bands will be better and I will have more power early, but for now I want the TBE and order the accessport later because they are still on backorder I heard.
Any opinions on getting the accessport first or the downpipe w/cat first. Thanks.
