Description

The SLP LoudMouth Cat-Back Exhaust is a performance upgrade designed for the Dodge Challenger. It's a cat-back style exhaust with a split rear, using a resonator instead of a standard muffler to deliver an aggressive, "wide-open" sound. Constructed from premium 304 stainless steel with mandrel-bent tubing, it ensures longevity, corrosion resistance, and optimized exhaust flow for maximum performance gains. The system is a direct-fit design, making installation hassle-free with no complex modifications required.
