BMW F40 M135i xDrive GPF - Scorpion turbo outlet front section with either high flow sports catalyst or cat delete

Unlock response and sound on your M135i xDrive F40 with this Scorpion turbo outlet front section. Choose a catted option for fast-flowing performance with a refined tone, or a catless track pipe for maximum gas speed on closed circuits. It is a direct bolt-on for GPF models and mates to the factory rear section or the matching Scorpion rear system, delivering a purposeful, motorsport-inspired soundtrack without fuss.

Why enthusiasts pick this upgrade

• Lower back pressure for sharper throttle pick-up and quicker spool compared to the restrictive factory primary catalyst
• Richer, deeper exhaust note that pairs perfectly with the stock rear system or a Scorpion rear section

• Plug-and-play installation using original mounting points and sensor locations
• Engineered specifically for GPF-equipped M135i xDrive F40 models

Options to suit your build
