ASM 70mm SS with Test pipe 
. if you dont get some type of tuning VAFC you will probably lose HP. At least I did 
when I put my stock cat back on 3HP gain through out the RPM range
Other mods where 70mm single, Mugen 2.2l header. Guess OBD 2 ecu's dont like mods without tuning. Maybe AP1' are better about this.
Good Luck!
