SLP Loudmouth II Exhaust System SRT-8 2005-12 Charger / 300C / Magnum.
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.
Each system is constructed from 3 stainless steel mandrel-bent tubing, for unrestricted flow with a integrated PowerFlo-X™ crossover pipe that will bolt to the factory 2.75 down pipes. Also, included is a pair of 4 double-wall polished tips w/SLP logo. Easy bolt-on installation and all hardware and installation instructions are included, backed by SLP's lifetime warranty.
Note: If upgrading to our Long Tube Headers use part# D30003 with 2.75 outlet down-pipes.
