For BMW F85 X5M S63 & BMW F86 X6M S63
Unlock the full performance potential of your BMW F85 X5M or F86 X6M (2014–2019) with the CTS Turbo Race Downpipe Set, engineered specifically for vehicles equipped with the powerful S63 4.4L Twin Turbo engine. Designed using advanced CAD technology and crafted from premium 304-grade stainless steel, these downpipes are a direct bolt-on replacement for the restrictive factory catalytic converters. Each unit is hand TIG welded and back-purged for superior durability and flow efficiency, ensuring long-lasting performance even under extreme conditions. With a 3" diameter and slip-fit design, installation is straightforward and requires no cutting or permanent modifications. Real-world tested for fitment and function, these downpipes deliver massive gains in power, throttle response, and turbo spool.
More than just a performance upgrade, the CTS Turbo Race Downpipes dramatically enhance your SUV’s sound profile. When paired with the factory exhaust, expect a deeper, throatier growl, aggressive exhaust crackles on downshifts, and a satisfying punch during high-RPM upshifts—all without unwanted drone. If you’re running an aftermarket exhaust system, the sound becomes even more pronounced. These downpipes are compatible with both left-hand and right-hand drive models (non-OPF/GPF only), making them a versatile and essential mod for enthusiasts looking to elevate both performance and driving experience. Combine them with tuning like bootmod3 to truly leave the competition behind and get the most out of your S63-powered BMW.
