SLP LoudMouth II Cat Back Exhaust for Challenger SRT8
Low Price Guarantee!
These systems provide a noticeable performance gain of up to 12 horsepower and are designed using SLP's innovative modular technology. This enables customers the flexibility to change the performance and noise-level characteristics by switching from our bullet-style Loud Mouth resonators, to our quieter Loud Mouth II mufflers in order to suit their individual requirements.
Each system is constructed from 3" stainless steel mandrel-bent tubing for unrestricted flow with an integrated 3.0" POwerFlo-X crossover pipe that will bolt to the factory 2.75" down pipes. Re-use your factory Challenger Square Exhaust Tips. Easy bolt-on installation and all hardware and installation instructions are included, backed by SLP's Lifetime Warranty.
NOTE: Designed to work with STOCK exhaust manifolds. If upgrading to our Long Tube Headers, use headers available below.
