Universal 4" Inlet/Outlet Performance Diesel Muffler - 20" Overall Length

Universal 4-inch inlet/outlet design, engineered to be a perfect upgrade for Cummins, Duramax, and Powerstroke diesel exhaust systems.

Features a 20-inch overall length, offering an ideal balance between effective noise reduction and a compact footprint for versatile installation.

High-flow internal design significantly reduces exhaust drone and cabin noise while maintaining unrestricted exhaust gas flow for maximum performance.

Constructed from heavy-duty materials to withstand the high-temperature exhaust gases and harsh conditions typical of diesel engines.

Ideal for custom exhaust builds or as a replacement for restrictive factory mufflers to achieve a deeper, refined diesel tone.

Compatible with most 4-inch aftermarket or custom-built diesel exhaust systems on light-duty and medium-duty trucks.

A must-have component for diesel owners looking to balance an aggressive sound with a comfortable, drone-free daily driving experience.
