MBRP Armor Plus 3-Inch Muffler Bypass with 4-Inch Tip

The MBRP S5013409 muffler bypass replaces the factory muffler on 2014-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 4.3L V6 or 5.3L V8 engine.

FAQ

Does this fit both single and dual exhaust configurations

This muffler bypass is designed for single exhaust configurations on the 4.3L and 5.3L Silverado and Sierra 1500. Verify your truck's exhaust configuration before ordering.

Is cutting required for installation
