Product Details

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.

Features & Benefits:

Enhanced exhaust tone
Simple installation (with instructions!)
Provides a massive 21 lbs in weight savings! (Factory muffler: 28 lbs, muffler delete: 7 lbs!)
Tip adjustment capability:
Slide farther for left and right adjustment
Rotate for vertical adjustment
Durable T304 stainless steel construction
Heavy-duty fabricated sheet metal exhaust hangers
Staggered dual exhaust tips provide an OEM+ finish and integrate perfectly in the factory rear valence
