Free Shipping Price: $839.99 (USD)
Part #: D31005
Bolt-on some serious power with a SLP Cat-Back Exhaust System. Now available from SLP is the stainless steel, Cat-Back Modular Exhaust System for the 6.1/6.4L Hemi-powered 2005-2014 Charger SRT-8, 2006-2008 Magnum SRT-8, and 2005-2014 Chrysler 300C SRT-8. It is available in Loud Mouth II® and Loud Mouth® designs. Thanks to the modular design, either mufflers or resonators can be ordered individually and interchanged separately.

These systems provide a noticeable performance gain of up to 12 horsepower and were 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 II mufflers, to our more aggressive bullet-style Loud Mouth resonators, in order to suit their individual requirements.

Each system is constructed from 3" stainless steel mandrel-bent tubing, for unrestricted flow with a integrated PowerFlo-X® crossover pipe that will bolt to the factory 2.75" down pipes. Also, included is a pair of 4" double-wall polished tips w/SLP logo. Easy bolt-on installation and all hardware and installation instructions are included, backed by SLP's Lifetime Warranty.

NOTE: This exhaust produces less back pressure then the stock exhaust. Because of the reduced back pressure some 6.4L SRT8 cars might display the SES light. Until tuning is available this light will remain on.

NOTE: If upgrading to our Long Tube Headers use part# D30003/D30003A/D30007 with 2.75" outlet down-pipes.
