For more information, visit www.P65warnings.ca.gov.The Scorpion High-Flow Sports Cat Downpipes (SBMX116) are a premium performance upgrade for the BMW F8X chassis (M2 Competition, M3, and M4). Specifically engineered for the S55 twin-turbocharged engine, these downpipes replace the restrictive factory units with high-performance 200-cell sports catalysts. This results in a massive reduction in backpressure, allowing the turbochargers to spool significantly faster and providing the breathing room necessary for high-horsepower Stage 2+ tuning applications.
Constructed from high-grade T304 stainless steel, these downpipes feature advanced thermal heat-shielding. The dimpled stainless steel outer layer is spot-welded to the pipe, creating a durable thermal barrier that reduces engine bay temperatures and protects sensitive components from heat soak. Beyond the performance gains, the Scorpion system amplifies the iconic S55 exhaust note, delivering a sharper, more aggressive, race-inspired sound profile.
Key Features:
- Maximum Flow Efficiency: 200-cell honeycomb sports catalysts offer significantly less resistance than the dense OEM catalyst structure.
- Advanced Heat Shielding: Features a dimpled stainless steel thermal layer to combat heat soak and protect the engine bay.
- Optimized Turbo Spool: Reduced backpressure results in sharper throttle response and faster boost onset.
- Race-Inspired Sound: Increases exhaust volume and clarity, providing a more visceral driving experience.
- Handcrafted Durability: Precision T304 stainless steel construction designed to endure the rigors of track use and high-boost environments.
- Tuning Ready: The ideal foundation for Stage 2 performance software and beyond.
Technical Specifications:
