Description
Upgrade your BMW S68-powered platform with MAD 300 Cell Race Catted Primary Downpipes, engineered for maximum performance gains, improved exhaust flow, and enhanced driving response. Designed and tested for the latest BMW S68 engines, these downpipes deliver a significant upgrade over restrictive factory components while maintaining reliability and drivability.
Performance Benefits
The factory downpipes restrict exhaust flow and limit the true potential of the S68 engine. By replacing them with MAD high-flow 300 cell catted downpipes, exhaust gases exit more efficiently, allowing the turbochargers to spool faster and operate more effectively.
Performance improvements include:
- Noticeable horsepower and torque gains
- Faster turbo spool and sharper throttle response
- Stronger midrange and overall power delivery
- Reduced exhaust backpressure
- Lower under-hood temperatures for improved efficiency
No Check Engine Light Guarantee
MAD 300 Cell catalytic converters are specifically engineered and tested to maintain catalyst efficiency readings on modern BMW engine management systems.
- Guaranteed No Check Engine Light for catalyst efficiency
- Free replacement if a catalyst-related CEL occurs
- 2-Year unlimited mileage warranty on catalytic converters
- Designed for long-term reliability and stability
Driving Experience Enhancement
