Ok I have a 2004 Saleen s281 with the magnaflow exhaust on it now. I wanted to switch to slp for some more sound. Now my car has a saleen tune in it and i was wondering if i switch catbacks if it will screw up the car. Thanks
I have never heard of something as simple as a catback interfearing with a tune, even something more extreem than a tune, the PC would be able to compensate.
