| Now available from SLP is a Stainless Steel Cat-Back Modular Exhaust System for the 2008-10 Challenger 6.1L 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 the bullet-style Loud Mouth™ resonators, to the 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. Re-use your factory Challenger Square Exhaust Tips. All hardware and installation instructions are included, backed by SLP's Lifetime Warranty.
