SLP PT# D31029
Now available from SLP is the Stainless Steel Modular Cat-Back Exhaust System for the 2009-13 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.

Should you get a Loudmouth I or II?
SLP's Loudmouth I (the item offered in this sale) exhaust utilizes SLP's unique shotgun resonators offer a very loud muscular sound similar to many power boats out there. These mufflers are very high flow, but are also loud enough to get unwanted attention at times.
SLP's Loudmouth II exhaust utilizes a straight through bullet muffler, which produces a deeper, less raspy sound than the Loudmouth I. While the Loudmouth II is quieter and will comply with most noise pollution laws, it is still one of the louder exhausts you can buy.
