2008-2013 Challenger 5.7L Loud Mouth Exhaust System

Bolt-on some serious power with a SLP Cat-Back Exhaust System. Now available from SLP is the Stainless Steel Modular Cat-Back Exhaust System for the 2009-2013 Challenger 5.7L HEMI R/T. It is available in Loud Mouth®, Loud Mouth II® and PowerFlo® designs. Thanks to the modular design, either resonators or mufflers can be ordered individually and interchanged separately. 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, or for that more civil muscular sound the PowerFlo mufflers in order to suit their individual requirements (cutting of rear pipes is needed to switch from the Loud Mouth Series to the PowerFlo Series). 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 2.5" 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.
