LoudMouth Cat-Back Exhaust System

The SLP LoudMouth Cat-Back Exhaust system is engineered to deliver a menacing and aggressive sound for your 1999-2004 Ford Mustang GT, Cobra, or Mach 1 equipped with the 4.6L V8 engine. Constructed from T304 stainless steel, this system ensures longevity and resistance to corrosion. It features mandrel-bent 2.5-inch tubing designed to maximize exhaust flow and enhance performance. At the heart of this system are SLP's "shotgun" race resonators, which provide virtually zero flow restriction, contributing to an audibly aggressive tone with deep tones during acceleration and deceleration. The exhaust is finished with dual 3.5-inch double-wall polished tips, electro-marked with the SLP logo for a premium look. Designed as a direct bolt-on application, this cat-back exhaust system is intended to install easily onto the factory mid-pipe, with an approximate installation time of 30 minutes for most users, though professional installation is recommended for those less experienced. The system is backed by an SLP limited lifetime warranty. This exhaust system fits 1999-2004 Mustang GT, 2001 Bullitt, and 2003-2004 Mach 1 models with the 4.6L engine.
