Transform your BMW 1 Series F20 or F21 114i, 116i or 118i with this premium rear section upgrade from Remus. This twin exit rear silencer with Street Race carbon-fibre sleeved outlets delivers a deeper, sportier soundtrack, sharper throttle response and a serious visual uplift. Built in Austria from high grade stainless steel with a bead-blasted finish, it is a favourite among our team and our customers for its quality, fit and unmistakable tone on the 1.6 turbo N13 engine.
Designed specifically for the petrol N13B16 models from 2011 onwards, this left and right dual-exit conversion replaces the factory back box and adds larger diameter pipework for increased flow. The 84 mm straight-cut carbon Street Race tailpipes sit perfectly to fill the rear valance, giving an OEM-plus look with motorsport vibes.
Why choose this rear section for your 1 Series
- Deeper, more pronounced exhaust note without sounding boomy
- Larger 65 mm Remus pipework versus the factory 52 mm tube for improved gas flow

- Austrian hand-crafted construction from corrosion-resistant stainless steel
- Lightweight design and precise fitment engineered for the F20 and F21 chassis
