304 Stainless High Performance Downpipe for BMW F10 F12 F13 M5 F06 M6
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.

FAQs
Please read our FAQs page to find out more.
Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
