SLP 2005-2014 Dodge Challenger/Charger/Magnum/300C 6.1/6.4L LoudMouth Cat-Back Exhaust System

Built with 2.5-inch mandrel-bent stainless steel tubing, this SLP LoudMouth cat-back exhaust system is designed to give your 2005-2014 Dodge Challenger, Charger, Magnum, or Chrysler 300 a more aggressive exhaust note. Specifically tuned for the 6.1L and 6.4L SRT-8 engines, it aims to improve the sound over the stock setup. The system uses SLP's LoudMouth muffler technology, which is known for its ability to produce a loud, race-inspired tone while still being manageable for daily driving.

This cat-back system replaces the factory mufflers and exhaust tips, connecting to your existing exhaust manifolds or a compatible mid-pipe. The stainless steel construction helps resist corrosion, which is important for longevity, especially in areas exposed to moisture and road salt. Mandrel bending ensures that the tubing maintains a consistent diameter throughout the bends, which helps with exhaust gas flow. This can contribute to a slightly improved throttle response and a more pronounced exhaust sound under acceleration.

Installation of this system typically bolts onto the factory exhaust hangers and connections. While it's designed to work with stock manifolds, you can also pair it with SLP's #D30003 or #D30003A mid-pipes for a more complete system. If you're looking to significantly change the sound of your SRT-8 Mopar vehicle and want a well-known name in performance exhaust, this SLP LoudMouth system is a solid option.
