Remus BMW 1 Series N13 F20 F21 Rear Sport Exhaust Silencer with Tailpipes (114i , 116i & 118i)

Transform the sound and flow of your BMW 1 Series petrol turbo

Give your F20 or F21 1.6 turbo four-cylinder the soundtrack and response it deserves with this premium Austrian‑built stainless steel rear box. This performance muffler replaces the factory rear section and delivers a deeper, sportier tone with reduced back pressure for improved throttle response. It features a centred can with a left and right single outlet and smart 84 mm tips for a purposeful OEM+ look.

We run this setup on customer cars and it never fails to impress. Clean fitment, great quality, and that addictive growl without drone. EC approved and backed by a 24‑month manufacturer warranty.
