BMW F20/F21 M135i and F22 M235i resonator delete is a simple yet effective upgrade designed to unleash a louder, sportier exhaust note from BMW’s N55-powered models. By removing the restrictive factory centre resonator, this precision-engineered pipe increases exhaust flow, sharpens throttle response, and adds an aggressive tone without compromising overall drivability.
Manufactured in the UK from T304 motorsport-grade stainless steel, our resonator delete is built for long-term durability, reduced weight, and seamless integration with the OEM backbox. It provides a cost-effective way to enhance sound and performance while maintaining perfect fitment.
Includes pipe and 2x clamps.
Compatibility List
The listing photos are generic, pipe sizing will vary depending upon your model.

Simply cut the standard exhaust at each side of the existing silencer and then clamp the new pipe into position. You will need to use exhaust assembly paste when fitting this part (not supplied).
