Scorpion Exhausts Non-resonated cat-back system - M135i 2012 - 2015

BMW M135i F20 F21 2012 to 2015 performance cat back by Scorpion

Unlock a sharper soundtrack and real-world performance with this British-built rear system for the BMW M135i. Crafted by Scorpion in the UK, this free-flowing, straight-through centre section and rear assembly replaces the pipework after the catalyst to deliver a deeper, more engaging tone and improved response on the N55-powered hot hatch.

Ideal for drivers seeking a louder, sportier character without touching the catalytic converter. This is a direct replacement that uses the factory mounting points and mates cleanly to original hardware, plus it is compatible with other Scorpion components.
