Do what I am doing, a CorkSport catted racepipe.Is there a HI-FO catalytic converter for the MS3? If so what are the recommendations? I need to have the car pass state inspection (yearly), but want greater gains.
The part number is AXE-6-114-14. You have to select options and the part number will change.What is the part number? I looked at the CorkSport site and the closest part i found was AXE-6-114-10.
Excellent! Do you think it is worth it? Meaning, are the gains over stock significant? Thank you for the link!
