Now available from SLP is the stainless steel, Catalyst-Back Modular Exhaust System for the 6.1L Hemi powered 2008-2014 R/T HEMI Challenger. Available in Loud Mouth™, Loud Mouth II™ and "PowerFlo" 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 a quieter Loud Mouth II™ mufflers, and the "PowerFlo" a quieter but noticeable note note.
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, and also MOTOBLUE HEADERS. If upgrading to SLP Long Tube Headers at the same time, contact us for details.
