4-Inch x 30-Inch Muffler Bypass Pipe

The MBRP muffler bypass pipe is a universal exhaust component designed to replace the stock muffler in 4-inch diesel exhaust systems for a more aggressive sound and optimized flow. Built as part of the Armor Lite series, this pipe features robust aluminized steel construction and is finished with handmade, premium manufacturing standards. It measures 4 inches at both the inlet and outlet with a 30-inch total length, providing a straightforward bolt-on solution for compatible exhaust configurations. Please note that this bypass pipe is not compatible with all diesel systems. It does not fit the 6.4L Ford, Chevy LMM, or 6.6L Dodge configurations. Always verify your specific exhaust diameter and vehicle compatibility prior to installation to ensure a proper fit. Each unit is backed by a 3-year manufacturer warranty, reflecting the durability of the materials used. As a universal-fit part, it is intended for use by installers looking for a simple, cost-effective way to delete an existing muffler section within a 4-inch piping setup.
