Classic Muscle Car Power And Sound. This SLP system includes SLP's Power Flow "straight-through" mufflers that are designed to provide an optimal balance of exhaust flow and sound level to free up more horsepower and to produce a classic muscle car rumble.
Superior SLP Construction. This SLP Axle-back system is made from mandrel bent 2.5" 409 stainless steel tubing for its excellent non-restrictive flow characteristics and long life. The system features two "straight-through" mufflers that end with brightly polished 304 stainless steel 4" tips, that are electro-marked with the distinctive SLP logo, giving a great finishing touch and a show quality look.
Application. Designed as a direct bolt on, this SLP Power Flow axle-back will bolt straight up to the factory piping without any modifications required on the 2005-2010 GT, 2008-2009 Bullitt, or 2007-2010 Shelby GT500 Mustangs to give it a classic throaty rumble.
