Product Details

SLP has been making performance parts for a long time, known for giving vehicles a more aggressive sound and improved performance. This LoudMouth cat-back exhaust system is built for your 2011-2014 Chrysler 300 with the 5.7L HEMI engine, designed to give your car a distinct, louder exhaust note that lets everyone know you mean business.

This system is a direct bolt-on replacement for your factory exhaust, using the stock exhaust manifolds as its starting point. The 'LoudMouth' design means it's engineered for a more pronounced sound than a typical exhaust, without being overly obnoxious for daily driving. It's constructed from durable materials to handle the heat and vibration of the exhaust system. You'll notice a more responsive feel from the engine, especially when you step on the gas, thanks to the improved flow over the stock setup.

When installing this system, you'll be working with a modular design that connects to your existing exhaust manifolds. It's a popular choice for owners looking to give their HEMI a more authoritative voice. Make sure you have the necessary tools for a standard exhaust system replacement, and refer to the manufacturer's instructions for the most accurate installation details.
