Rob,
I realize that downpipes make a big difference in power and are better for the turbos. As replacing stock cats is illegal technically even if replaced with catted dps, I would hope that there is a stage that can make use of an intake, FMIC, and catback exhaust.
-It is illegal to modify the stock catalytic converter on any car unless that catalytic converter has failed and there is documentation to support this assertion.-
This would essentially allow for something more than stage 1 without illegally modifying your car.
Disclaimer: I will run catless downpipes in the future. While my warranty is intact however, I will run stock downpipes. I don't really give a shit about the legality, I just don't want to fry my turbos or roast my stock cats on stage 2.
