SLP 2008-2014 Dodge Challenger/Charger/Magnum/300C 5.7L LoudMouth Cat-Back Exhaust System - D31029

Bolt-on some serious power with a LoudMouth Cat-Back Exhaust System. Now available from LoudMouth is the Stainless Steel Modular Cat-Back Exhaust System for the 2009-2014 Challenger 5.7L HEMI R/T. It is available in LoudMouth®, LoudMouth 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 LoudMouth's innovative modular technology. This enables customers the flexibility to change the performance and noise-level characteristics by switching from SLP's bullet-style resonators, to SLP's quieter 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 LoudMouth 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. NOTE: Designed to work with STOCK exhaust manifolds.
