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 Catback 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.

    Perfect exhaust system for those that do not want excessive noise at cruising speeds. Nice deep tone. Kit fit perfectly. Some pipe connections were fairly loose and clamps needed to be tightened up a lot, other than that it was an easy installation. Tips look better than stock.

    Exactly what I was looking for! If you have headers and mid pipe this exhaust is perfect. It gives your pony that healthy rumble, while not being over the top loud at the same time. I had the slp lm1s and they just made noise. With the power-flo i actually picked up some bottom end! Thanks American Muscle for a fast delivery and a great product!

    I received my SLP system only a couple days after my order was placed and had them installed the next day. It gives the car a deep growl without any drone at speed and the tips looks great out the back of the car.
