SLP Power-Flo Cat-Back Exhaust (99-04 GT, Mach 1)Find parts that fit my vehicle

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.

Modular Design. SLP's unique modular design allows you to quickly and easily switch out the mufflers or resonators to suit your driving needs. Along with the included Power Flow Mufflers, the Power Flow catback system is compatible with all SLP mufflers and resonators including the bullet-type Loud Mouth II and the shotgun-style Loudmouth Resonators.

Superior SLP Construction. This SLP Cat-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 ends with brightly polished 304 stainless steel 3.5" tips, that are electro-marked with the distinctive SLP logo, giving a great finishing touch and a show quality look.

Application. Designed to be a direct bolt on, this SLP Power Flow catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 1999-2004 GT, 2001 Bullitt, or 2003-2004 Mach 1 Mustang to give it a classic throaty rumble.
