Evolve 4-1 Stepped Medusa Headers for BMW E39 M5 S62 V8 LHD - T304 Stainless Performance Exhaust Manifolds Made in Italy
For left hand drive BMW E39 M5 S62 V8 only
Unlock real E39 M5 performance with the Evolve 4-1 Stepped Medusa headers. The stock BMW E39 M5 exhaust manifolds are the biggest restriction on the S62 V8. Cat back systems alone deliver little real power on this platform. These Evolve stainless steel performance manifolds remove the bottleneck for measurable horsepower and torque gains across the entire rev range, with stronger midrange and harder top end pull.
Designed specifically for the S62 V8, the 4-1 stepped primary layout builds low and midrange torque while adding top end power. Where many aftermarket E39 M5 headers lose torque below 5000 rpm, the Evolve Medusa design keeps the S62 punch intact. Expect almost 400 lb ft from 2000 to 5000 rpm with the right setup, faster real world acceleration and sharper throttle response.
Proven power gains
- Minimum gains from headers alone: 25 to 30 bhp and 25 to 27 lb ft
- Above 5000 rpm: typical increases of 25 to 40 hp depending on engine condition and supporting mods
- Biggest single performance upgrade for the E39 M5 S62 V8
Sound is purposeful without being intrusive. With headers alone, volume rises slightly and adds a motorsport tone without drone. Pair with an Evolve exhaust for more sound if desired.

Maximise your E39 M5 upgrade
