Upgrade your BMW 125i F20 F21 B48 engine with the Milltek Rear Silencer Bypass Non-Valved Louder system with GT-90 Titanium Trims. This rear box delete rear silencer delete transforms the sound and look of your car, delivering a harder edged exhaust note and a premium titanium tailpipe finish designed to suit the M135i rear valance. Perfect for drivers who want a Milltek Sport exhaust tone that is sporty and crisp without intrusive drone, NVH or cabin resonance.

Every Milltek exhaust is designed, developed and hand finished in the UK in aerospace grade type 304 non-magnetic stainless steel. This superior material is less susceptible to discolouration and is used throughout the pipework, silencers and associated hardware. Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to deliver performance without sacrificing mid-range torque. Acoustic development is comprehensive to achieve that signature Milltek sound.
