what kind of exhaust should i use with my h22 swap? i want unrestrictive, yet stock looking and sounding (i believe i will use a qtec cutoff somewhere to relieve cat pressure at the track ) all i can find are 60mm pipes and i thought i'd want at least 2.5 inch pipes (i belive 60mm is 2.25) not to mention what kind of downpipe would i need to connect my turbo to the exhaust?

REMINDER: i have a 96 gen5 4door
