Now available from SLP is the stainless steel, Catalyst-Back Modular Exhaust System for the 6.1L Hemi powered 2008 SRT-8 Challenger. 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 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 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 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. Easy bolt-on installation and all hardware and installation instructions are included, back by SLP's Lifetime Warranty.
NOTE: Designed to work with SLP Long Tube Headers part# D30009.
NOTE: This part is not compatible with the Challenger SRT8 equipped with a 6-speed manual transmission.
