Take your BMW S68-powered platform to the next level with the MAD 300 Cell Race Catted Primary Downpipes. Developed and extensively tested on the latest generation of BMW S68-powered vehicles, these downpipes are engineered for drivers who want substantial performance gains, an enhanced exhaust note, and the confidence of our industry-leading No Check Engine Light Guarantee.
Performance Benefits
The restrictive factory downpipes limit your S68's true capability. By upgrading to the MAD 300 Cell Race Catted Downpipes, exhaust flow is significantly improved, allowing the turbochargers to spool faster and operate more efficiently. The result is sharper throttle response, stronger midrange power, and a more engaging driving experience throughout the RPM range.
No Check Engine Light Guarantee
Unlike many aftermarket catted downpipes, the MAD S68 Downpipes utilize premium 300 Cell High-Flow Catalytic Converters specifically selected and tested to maintain proper catalyst efficiency readings on the latest BMW engine management systems.
We stand behind our design with a No Check Engine Light Guarantee. If you experience a catalyst-related check engine light, MAD will replace the downpipes free of charge.
For additional peace of mind, our No CEL downpipes also include a 2-Year Warranty on the catalytic converters with no mileage limitations, making them one of the most comprehensive catted downpipe offerings available for the S68 platform.
Enhanced Driving Experience
Along with the performance improvements, the MAD downpipes transform the exhaust character of your S68-powered BMW. Expect a deeper, more aggressive exhaust note with increased turbo sound while maintaining the refinement expected from a modern BMW performance vehicle.
Improved exhaust flow also helps reduce exhaust backpressure and lower under-hood temperatures, contributing to long-term turbocharger reliability and efficiency.
Precision Construction
Each downpipe is manufactured from heavy-duty 2.0mm wall 304 stainless steel, chosen for its durability and ability to withstand extreme temperatures.
Our TIG welding and back-purging process ensures exceptional weld integrity while maintaining smooth internal surfaces for maximum exhaust flow.
Designed as a direct bolt-on upgrade, the system utilizes OEM-style flanges and mounting points for straightforward installation and factory-like fitment.

Unlike generic alternatives, MAD downpipes are specifically engineered for the S68 platform and validated across multiple applications including the X5M, X6M, XM, and the latest G90/G99 M5 models.
