Evolve Long Tube Manifolds for BMW E60 E61 M5 and E63 E64 M6 — High Flow Stainless Steel Headers for S85 V10
Evolve long tube manifolds for the BMW M5 and M6 are a proven performance exhaust upgrade for the S85 V10. These tubular headers remove the highly restrictive primary catalytic converters and use long tube, larger diameter pipework to dramatically improve exhaust flow, power and torque across the rev range. If you are searching for BMW M5 headers, BMW M6 headers, S85 long tube headers, E60 M5 exhaust manifolds, E63 M6 decat headers, BMW V10 headers, stainless steel performance exhaust manifolds or Evolve headers UK, this is the go-to solution for unlocking serious performance.
Designed for maximum performance, these Evolve tubular headers deliver substantial gains versus the stock manifolds thanks to a flow-optimised 5-1 step design and a motorsport-style merge collector. Expect sharper throttle response, stronger mid-range and a harder-hitting top end with the signature V10 sound enhanced.
Performance Gains
Real-world results and dyno testing show performance gains of between 35-50 hp and 40-50 lb.ft of torque when correctly calibrated. By eliminating the primary catalytic converters and using a long tube layout, back pressure is significantly reduced and exhaust scavenging is improved for meaningful horsepower and torque increases.
Key Features
- Constructed from 304 grade stainless steel for durability and heat resistance
- 5-1 step design header for optimal exhaust pulse tuning
- F1 style TIG welded, flow-optimised slip-on merge collector
- Full TIG welded construction
Fitment
- BMW E60 M5 5.0 V10 S85
- BMW E61 M5 Touring 5.0 V10 S85
- BMW E63 M6 5.0 V10 S85
- BMW E64 M6 Convertible 5.0 V10 S85
ECU Tuning Required for Best Results
The radical long tube, low back pressure design changes the engine’s flow characteristics compared to the smaller diameter, high back pressure stock header system. To achieve the best performance throughout the RPM range, recalibration of the DME is essential. This includes appropriate changes to ignition timing, fuel mapping and VANOS control so the S85 can fully exploit the increased flow. The stock calibration is not optimised for this setup.
Why Choose Evolve Long Tube Headers for the S85 V10
- Substantial horsepower and torque gains with correct ECU calibration
- Enhanced exhaust tone and responsiveness
- High quality 304 stainless steel, TIG welded for strength and longevity
- Flow-optimised collector and step design derived from motorsport principles
- Proven upgrade for track-focused BMW M5 and M6 builds
Our Experience and Customer Feedback
We have installed and used these Evolve long tube manifolds on customer BMW M5 and M6 S85 cars, and feedback has been consistently excellent. Owners report stronger mid-range pull, a more urgent top end and an addictive V10 soundtrack, backed up by measurable gains when paired with the correct ECU calibration.
Fitting and Calibration
Professional installation and ECU recalibration are strongly recommended to maximise performance and ensure drivability. For fitting and tuning support, choose Nforcd in Warwickshire. Request a quote at Sales@nforcd.com.
Important Notes
- Eliminates the primary catalytic converters. Intended for off-road or track use where applicable. Check local laws and regulations.
- ECU remap required to optimise ignition, fuel and VANOS maps for the long tube design.
