I recently ordered a 2013 Mustang V6 PP and am interested in modifying the exhaust. I'm seriously considering the Magnaflow Competition Cat Back. I think the cat back is the way to go because I'm looking to increase the power slightly, not just the sound. Is there any issues with warranties when running an aftermarket cat back exhaust? My first priority is maintaining my warranty.

 

No exhaust warranty, but that's about it.
