Bolt-on some serious power with a Cat-Back Exhaust System LoudMouth.
Now available from LoudMouth is the Stainless Steel Modular Cat-Back Exhaust System for the Challenger 5.7 Liter HEMI R/T from 2009-2014.
It is available in LoudMouth, LoudMouth II, and PowerFlo designs.
Thanks to the modular design, either mufflers or resonators can be ordered individually and interchanged separately.
These systems are designed using LoudMouth's innovative modular technology and provide a noticeable performance gain of up to 12 horsepower.
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.
