2008-2012 Dodge Challenger, 5.7L, Loud Mouth II 

Now available from SLP is the stainless steel, Catalyst-Back Modular Exhaust System for the 5.7L 2008-2012 Challenger. It is 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 our bullet-style Loud Mouth II™ mufflers, to our louder Loud Mouth™ resonators or our more civil but muscular sounding PowerFlo system (cutting of rear pipes would be needed) in order to suit their individual requirements.

Each system is constructed from 3" stainless steel mandrel-bent tubing, for unrestricted flow with an integrated 3" PowerFlo-X™ Crossover Pipe that will bolt to the factory 2.5" 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.

Loud Mouth II™ catalyst-back exhaust system for 5.7L features:
  • Stainless Steel, 3" mandrel-bent tubing
  • Polished Loud Mouth II ™ mufflers w/SLP's logo embossed in the body
  • Integrated PowerFlo-X™ Crossover Pipe w/2.5" Inlet
  • Factory Style Ball-Band Clamps included to re-use factory Challenger Tips
  • Easy, bolt-on installation and SLP's lifetime warranty
  • All hardware and installation instructions are included

No discounts can be taken on SLP products. The price shown in our lowest price available.
