Went to emissions today and passed the obd2 test just didnt pass the visual bc it has no cats. The car has a ms3 cam and the normal bolt ons and tuned. Will adding highflow cats to the car affect the tune or will it be fine and not change anything. will buying some and gutting them be better? The rear 02s have been turned off in the tune. Anyone know where to get some cheap 3inch cats?

you can get cat "look alikes" or just small tubes that look like cats but actually arent. I forget who sells them though, and if you did want to add them they shouldnt effect the tune enough to matter
