SLP Performance - 05-10 SRT-8 Charger/Magnum/300C "Loud Mouth" Cat-Back Stainless Steel System use w/ stock manifolds Now available from SLP is the stainless steel, Catalyst-Back Modular Exhaust System for the 6.1L Hemi powered 2005-2007 SRT-8 Dodge Charger/Magnum and Chrysler 300C. It is available in Loud Mouth™ and Loud Mouth II™ 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 were 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, in order to suit their individual requirements.
