Scorpion BMW F90 M5 & M5 Competition Axle Back Exhaust System (Pre-LCI & LCI)

Transform the sound and character of your BMW M5 with the Scorpion Axle Back Exhaust System, engineered specifically for the BMW F90 M5 and M5 Competition. Designed and manufactured in the UK using premium T304 stainless steel, this axle-back system delivers a deeper, more aggressive exhaust note while retaining compatibility with the factory exhaust layout.

Developed for both Pre-LCI and LCI F90 M5 models (2017-2022), the Scorpion axle-back system replaces the factory rear silencer section to unlock more of the S63 twin-turbo V8's unmistakable soundtrack. The result is a richer exhaust tone with enhanced V8 character, improved driver engagement and a premium rear-end appearance thanks to a choice of Scorpion's signature tailpipe finishes.

Unleash the S63 V8 Soundtrack

• Improved exhaust presence without excessive cabin drone

Whether cruising on the motorway or accelerating hard through the gears, the Scorpion system allows more of the S63's performance character to be heard.

• Long-term durability
• Precision-engineered fitment
• Consistent exhaust flow

The 80mm pipework has been engineered to complement the performance characteristics of the F90 M5 platform while maintaining OEM-level fitment.
