Scorpion GPF-Back Exhaust System For BMW F40 128ti

The Scorpion GPF-Back Exhaust System for the BMW F40 128ti is a precision-built performance upgrade designed to improve flow, enhance sound, and reduce weight compared to the factory setup. Specifically developed for GPF-equipped 128ti models (excluding Australian models), this system uses 70mm (2.75”) T304 stainless steel mandrel-bent pipework for maximum durability and optimised gas flow.

This system retains valve control, requiring the OE motor for full functionality. It fits directly to OEM or Scorpion components, though cutting of the original exhaust is required unless fitted in combination with Scorpion’s SBMP085 section. Available with a choice of two distinct tailpipe finishes, the system allows drivers to tailor the look of their car:

• SBM085 – Polished 114mm Daytona Tailpipes

• SBM085CF – Carbon Fibre 114mm Ascari Tailpipes

Designed, developed, and manufactured in the UK, Scorpion exhausts deliver performance, reliability, and an unmistakable exhaust tone, all backed by Scorpion’s lifetime guarantee*.
