BMW M135i F20 Resonator Delete Pipes

Resonator Delete Pipes are all about freeing up the character that is already there in your BMW M135i F20. The factory resonator is designed to smooth out noise and keep things civil, which is fine for daily driving, but it also kills a lot of the natural exhaust note. Swapping to a resonator delete pipe gives a louder, crisper sound with more presence, especially under load and on spirited drives.

Most Resonator Delete Pipes kits are a straightforward section replacement, so you are not redesigning the whole exhaust, just removing a restriction and some dead weight. You will typically notice faster rev pick up and a slightly more responsive feel, although the main benefit is the more aggressive tone and extra character on throttle and overrun. It pairs nicely with other exhaust upgrades in the Exhaust range, like back boxes or cat back systems.

We always suggest thinking about your use case first. If your BMW M135i F20 is a daily, be aware that some extra cabin noise and potential motorway drone can come with a resonator delete, depending on gearbox, gearing and road speed. For weekend toys and track builds, it is usually a no brainer, giving that motorsport flavour without the cost of a full custom system. Quality stainless steel construction and proper fitment are key, so stick to proven brands that match the OE layout and mounting points.
