Bolt-on some serious power with a SLP Cat-Back Exhaust System Now available from SLP is a Stainless Steel Cat-Back Modular Exhaust System for the 2008-2013 Challenger 6.1L/6.4L SRT-8 and 5.7L R/T. 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 PowerFlo-X® crossover pipe with full 3" down-pipes, which bolt to SLP Long-Tube headers.
