ECS N20 Muffler Delete Kit - F30/F31/F32/F33/F36

Transform the sound profile and driving dynamics of your BMW without replacing the entire exhaust system! Engineered specifically for the N20-equipped F3X platform, this direct-fit muffler delete delivers an aggressive, sporty tone you wouldn't expect from a 4-cylinder engine.

By eliminating the restrictive factory muffler and replacing it with a high-flow, straight-through exhaust pipe, this kit unlocks an incredible surge in volume and a sporty tone. Beyond the dramatic sound upgrade, this setup drastically improves performance efficiency through massive weight savings. The high-flow straight pipe removes 21 lbs from the rear of the vehicle, dropping the total axle-back exhaust weight down to just 7 lbs. Designed for quick at-home installation, it installs using basic garage hand tools and integrates perfectly with your OEM rear valance for a clean, OEM+ aesthetic.
