When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

For the owner of the G90 M5 who demands both high performance and environmental responsibility, Active Autowerke offers the GESI Catted Downpipes. These units feature genuine GESi G-Sport Ultra High Output Catalytic Converters, which are EPA-registered and fully OBD2 compliant (excluding California). Utilizing proprietary precious metal loading, these 400-cell catalysts reach operational efficiency within just 9 seconds of startup, drastically reducing emissions and eliminating the raw fuel smell common with catless systems. Hand-made in Miami, FL, and constructed from heavy-duty 304 stainless steel, these downpipes provide a durable, high-quality performance upgrade that integrates seamlessly with factory mounting points. Key Features: EPA Registered & Compliant: 49-state legal and fully OBD2 compliant for 1996+ vehicles. Cast Stainless V-Bands: Features precision-casted upper V-bands for a perfect, leak-free seal to the turbochargers. Reduced Radiant Heat: Lowering backpressure helps pull heat away from the turbochargers and engine components. Precision Fabrication: Meticulously TIG welded and test-fitted on a dedicated G90 M5 fixture. Standard-Setting Reliability: The 304 stainless substrate is furnace-braised to the mantle for outstanding resistance to vibration. Specifications: SKU: 11-142. Inlet Type: Precision Casted Stainless V-Band. Substrate: Metal core 400 CPSI catalyst. Warranty: 5-year/50,000-mile warranty on shell/tube ends; 2-year/25,000-mile on catalyst core (void if excessive burble tune is used). Manufacturing: Made in Miami, Florida, USA. Vehicle Fitment: 2025+ BMW M5 (G90 Sedan and G99 Touring) with the S68 V8 Hybrid engine.
