Bolt-on some serious power with a SLP Cat-Back Exhaust System

Now available from SLP is the Stainless Steel Modular Cat-Back Exhaust System for the 2009-12 Challenger 5.7L HEMI R/T. 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® resonators, to our quieter Loud Mouth II® mufflers, or for that more civil muscular sound the PowerFlo® mufflers in order to suit their individual requirements (cutting of rear pipes is needed to switch from the Loud Mouth® Series to the PowerFlo® Series). 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 2.5" 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. If upgrading to our Long Tube Headers use part #D30005 (Headers) Loud Mouth® Cat-Back Exhaust System for 5.7L R/T features:
