BMW 1 Series 125i F20 F21 Performance Rear Exhaust Box (Stainless) – OE 18302293763 – Tipless

Upgrade the sound and quality of your 1 Series without compromising OEM integrity. This official BMW performance rear section is a direct replacement end silencer for the 125i hatchback (F20 five‑door and F21 three‑door). Built from high‑grade stainless steel and tuned by BMW engineers, it delivers a richer, sportier tone with excellent refinement, factory fitment and long‑term reliability. If you want an authentic, bolt‑on, tipless rear box that looks stock but sounds purposeful, this is the one to choose.

We’ve installed this unit on multiple customer cars at MJ Modifications in Warwickshire and the feedback is consistently positive. Owners love the deeper note, the OEM+ character, and the clean fit using the original mounting points. It’s the ideal choice if you’re after a subtle performance sound and genuine BMW quality.
