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!
