SLP D31029 Exhaust System 2008-2014 5.7L Challenger LoudMouth

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 5.7 Liter 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 our bullet-style resonators, to our 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.
