The TurboXS doesn't have a cat in the downpipe btw the o2 sensors from what i can see. Looks like a similar bell mouth to the CPE/COBB DP. The Corksport is the only Downpipe that has a divorced downpipe which is meant to be better for spooling up( ie comes on a little lower than a straight bell mouth design). What's better? that's up for discussion.
Having said that, I had to get a custom cat made up to make my exhaust straight through system cause the stock cat isn't good enough.
The CPE and Cobb ones are the only downpipes that bolt directly up to the standard cat back exhaust AND contain a proper High Flow Cat in it. If i had my time again, I would be going for a CPE Downpipe...
