Scorpion Non Resonated Cat Back Exhaust System For BMW F20 & F21 M135i (including xDrive Models)

The Scorpion Non-Resonated Cat-Back Exhaust System for the BMW F20/F21 M135i (including xDrive models) is a high-performance upgrade designed to unlock a louder, more aggressive exhaust note and improved flow compared to the restrictive factory system. Built with 80mm (3.15”) T304 stainless steel mandrel-bent pipework, this system reduces back pressure, sharpens throttle response, and enhances the driving experience of BMW’s N55-powered hot hatch.

Available in two variations, the system allows owners to choose the setup that best suits their driving style:

• With Valve – retains factory valve functionality for switchable sound modes

• Without Valve – for a consistent, more aggressive exhaust tone

To complete the look, the system is offered with three premium tailpipe finish options:

• Polished 100mm Daytona Tailpipes

• Black Ceramic 100mm Daytona Tailpipes

• Carbon Fibre 100mm Ascari Tailpipes
