Maximize the performance and sound of your BMW S63-powered M5 or M6 with the STRATEC™ High-Performance Downpipes. Precision-engineered for the 4.4L Twin-Turbo V8, these downpipes significantly improve exhaust flow, reduce turbo backpressure, and unleash a more aggressive exhaust note while enhancing throttle response and overall engine performance.
Constructed from premium automotive-grade T304 stainless steel, every STRATEC™ downpipe is CNC-manufactured and hand TIG welded to ensure exceptional durability, corrosion resistance, and OEM-quality fitment.
Available in 200-Cell High-Flow Sport Catalytic or Catless Race configurations, STRATEC™ Downpipes allow you to choose the perfect balance between performance and your intended application. For added convenience, the catless version includes O₂ sensor spacers to help reduce the likelihood of catalyst efficiency fault codes when used on applicable vehicles.
Whether paired with the factory exhaust or an aftermarket cat-back system, STRATEC™ Downpipes unlock the true sound and performance potential of the S63 twin-turbo V8.
