Here's the thing, for a catback, you don't need a tune. If you change out the Jpipe and or go with a turbo back, you'll need to pull the secondary restrictor pill and also run a tune. For warranty purposes, it is up to the dealer as they could say well X co tributes to Y. Some dealers are prickish others are cool but obviously won't warranty the 'said' installed part.
I went with the TurboXS Jpipe and Corsa catback. Running a pro tune and EGR block off.
