Take your 2024+ BMW X5M or X6M Competition to the next level with the MAD Catless Primary Downpipes for the S68 engine. Engineered for drivers who want uncompromised performance and an aggressive exhaust note, these downpipes free up horsepower and unlock the raw potential of your M.

Performance Benefits

The restrictive factory downpipes limit your S68’s true capability. Swapping to MAD catless downpipes improves exhaust flow, allowing the turbos to spool quicker and respond faster. The difference is immediate sharper throttle response, improved midrange punch, and an overall more exciting driving experience.

Enhanced Driving Experience

Along with performance gains, the MAD downpipes transform your exhaust tone. Expect a deeper, more powerful sound without sacrificing refinement. Lower under-hood temperatures also help preserve long-term turbo health, making this upgrade about both performance and longevity.

Precision Build

Each downpipe is crafted from thick 2.0mm 304 stainless steel, chosen for durability and resistance to high heat. Our TIG welding and back-purging process ensures maximum strength and smooth interior surfaces for uninterrupted airflow. Designed as a direct bolt-on upgrade, installation is straightforward with OEM-style brackets and flanges.

Why Choose MAD?

Unlike generic alternatives, MAD downpipes are designed specifically for the S68 platform with fitment tested on the X5M and X6M. We stand behind our work with a limited lifetime warranty, giving you peace of mind while you enjoy the performance benefits.
