Unleash the full performance potential of your BMW X5M or X6M with the German Car Accessories S63 Performance Downpipes. Engineered specifically for the 2015-2018 F85 X5M and F86 X6M equipped with the legendary 4.4L Twin Turbo S63 V8 engine, these high-flow downpipes are designed to maximize exhaust efficiency, turbocharger response, and overall engine performance.
By replacing the restrictive factory downpipes, these performance downpipes dramatically improve exhaust gas flow and reduce backpressure. The result is faster turbo spool, improved throttle response, increased horsepower and torque potential, and a more aggressive power delivery throughout the RPM range.
In addition to the performance gains, these downpipes unlock the true sound of the S63 Twin Turbo V8. Expect a deeper, more aggressive exhaust note with enhanced turbo acoustics that provide a significantly more engaging driving experience.
Manufactured from premium T304 stainless steel, these downpipes are built to withstand extreme temperatures and demanding performance applications. Precision TIG-welded construction ensures exceptional strength, durability, and long-term reliability while maintaining optimal exhaust flow characteristics.
Designed as a direct-fit solution for F85 and F86 models, these downpipes integrate seamlessly with the factory exhaust system for straightforward installation and OEM-like fitment.

Why Upgrade Your Downpipes?
The factory downpipes on the S63-powered X5M and X6M are designed with emissions and noise restrictions in mind, which can limit exhaust flow and overall performance. Upgrading to high-flow performance downpipes removes these restrictions, allowing the twin turbos to operate more efficiently. The result is improved power delivery, quicker throttle response, enhanced turbo performance, and a significantly more aggressive exhaust note that transforms the driving experience.
