CS, CPE, ATP, get whatever is the cheapest you can find.... the ebay/M2 dp is your choice to use... catless, the car is pretty loud when you get on WOT... idle is not too bad....
get some extra hands to help you
yes is have thee CS shorty and a turboxs race pipe, with a CP-e 3" single catback
Dud you have any trouble with the CS shorty mating to the Turbo xs race pipe. Or issues with the wastegate
You should have no problems with our downpipe mating to the SU test pipe you have. The DP includes an O2 spacer to keep the cel off.
