Bolt-on some serious power with a SLP Cat-Back Exhaust System Now available from SLP is a Stainless Steel Modular Cat-Back Exhaust System for the 2008-2013 Challenger 6.1L/6.4L HEMI SRT-8. It is available in Loud Mouth® and Loud Mouth II® 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, in order to suit their individual requirements.
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 2.75" 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. If upgrading to our Long Tube Headers use part# D30008 (Headers)
