What about car back vs axel back? Any evidence you get a performance boost with cat back? Was thinking about going with the Corsa Performance Sport Cat-Back
Does k&n cold air intake work well along with the ford performance tune? I got it for my 2.7L just want to know if needs unique programming or can just be installed to engine with FP tune
The standard skid plate protects the engine right? Which under armor would would you recommend adding? Fuel, transmission, crossmember, transfer case protection?
