More Power and Sound. This SLP system includes SLP's infamous Loudmouth "shotgun" race resonators that offer virtually no exhaust flow restrictions to free up more horsepower and to produce the most aggressive sound possible.

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 resonators, the Loud Mouth system is compatible with all SLP mufflers and resonators including the bullet-type Loud Mouth II and the traditional-style PowerFlo Muffler.

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 turn-down tips, that exit in the stock location giving a great finishing touch and a show quality look.

Application. Designed as a direct bolt on, this SLP Loudmouth catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 1986 to 1993 GT Mustangs to give it a rich, throaty sound.

NOTE: Includes Loud Mouth resonators. Loud Mouth II and PowerFlo mufflers sold separately!

    I love the way this kit sounds! Has a very aggressive tone and will definitely make your 5.0 stand out from the Flowmaster crowd. Easy to install, took about an hour on a lift to install, including a Pypes 304 SS O/R X-pipe. Only thing I didn't like was that I could not make the exhaust tips point out from under the car, they're hidden by the bumper. Other than that I give it 5* for an excellent product at a great price!

    It's a really good exhaust system, it not only improved the way my Mustang sounds, it also improved air flow which gave me added horse power.
