BMW Axleback Exhaust for BMW 4 Series F33 (2014+)

Arguably THE BEST modification for your B46/B48. This muffler delete sounds too good to be a 4 cylinder! The combination of B48 and muffler delete surpasses all sound expectations from a 4-cylinder! Impressive direct-fit solution. With this new muffler delete you can transform the sound and driving experience of your 330 or 430. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage!

The ECS B48 muffler delete removes the heavy and restrictive factory exhaust muffler and replaces it with a high-flow, straight-through exhaust pipe. This adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. The muffler delete creates a noticeable increase in exhaust sound and more exhilarating turbo noise, without adding significant drone at cruising speeds. As an added bonus, our muffler delete shaves off 21.0 lbs., weighing in at only 7.0lbs compared to the OEM muffler at 28.0lbs!
