SLP Performance

Though they're better known for all the work they do for ''those'' Camaro guys, SLP Performance makes some of the most awesome Mustang exhaust kits and components available on the aftermarket. SLP has it all, from Mustang long tube headers, x-pipes, cat-back kits, and even axle-back kits for the newest of generations of Mustang. SLP's best selling Mustang exhaust kits are their Loud Mouth series of cat-back and axle-back exhausts that completely delete mufflers from their designs to create the some of the loudest exhaust roars out there with minimal installation time and at an extremely low cost. SLP is your one stop Mustang exhaust upgrade manufacturer that can net you huge power and torque gains, with a vicious sound, to boot.
