I've been doing a lot of research regarding DP's and turbo back exhausts and was wondering if the experts can chime in here.
#1. If I got a set of Cattless AR Dp's with PE (leaving the secondary catts in) would I still be able to pass emissions?
#2. If I got a set if catted AR DP's with PE (removing secondary catts) would I still be able to pass emissions?
Which set-up would be better performance wise (I'm assuming #1 for turbo breathability) and would either method still pass emissions.
because as you all know, we have very strict emissions laws here in Ontario.
