The LoudMouth Cat-Back Exhaust System for the 2008-2014 Challenger 6.1L/6.4L HEMI SRT8 is now available in LoudMouth and LoudMouth II designs.�The stainless steel modular cat-back system is so technologically advanced, that you can change the performance and noise-level characteristics of your Challenger simply by swapping out the bullet-style resonators (included) to milder SLP mufflers (Part #31067).

You�ll notice performance gains of up to 12 horsepower after installing the system, which is constructed from 3-inch stainless steel mandrel-bent tubing for unrestricted flow with an integrated 3.0-inch PowerFlo-X crossover pipe that bolts to the factory 2.75-inch down pipes.

The factory Challenger square exhaust tips fit this exhaust system, and installation is easy � all hardware and installation instructions are included.

NOTE: Designed to work with STOCK exhaust manifolds. If upgrading to SLP Long Tube Headers, use part# D30008.
