Description
Upgrade your BMW S68-powered platform with the MAD BMW 2024+ S68 Primary Catted Downpipes featuring high-flow 300 Cell catalytic converters and No Check Engine Light (No CEL) design. Engineered for the latest generation of BMW performance SUVs and M models, these downpipes are designed to unlock significant performance gains, improved exhaust flow, and a more aggressive exhaust character while maintaining emissions catalyst efficiency compatibility.
The factory S68 downpipes are restrictive and limit turbocharger efficiency. The MAD 300 Cell Race Catted Downpipes reduce exhaust restriction, allowing faster turbo spool, improved airflow, and more responsive throttle behavior. Drivers will experience noticeable gains in midrange torque, sharper acceleration, and a more engaging driving experience across the RPM range.
Built specifically for modern BMW engine management systems, these downpipes are tested to maintain proper catalyst efficiency readings. This ensures reliable operation with a No Check Engine Light Guarantee, giving added confidence when upgrading your exhaust system.
Each unit is constructed from heavy-duty 304 stainless steel with a 2.0mm wall thickness for maximum durability under high exhaust temperatures. Precision TIG welding with back-purging ensures strong, clean welds and smooth internal flow characteristics for optimal performance. OEM-style flanges and mounting points provide direct bolt-on installation and factory-like fitment.
In addition to performance improvements, the MAD S68 downpipes enhance the overall driving experience with a deeper, more aggressive exhaust tone and increased turbo sound, while still maintaining refinement suitable for modern BMW M vehicles. Reduced exhaust backpressure also contributes to lower under-hood temperatures and improved turbocharger efficiency.
These downpipes are extensively tested across multiple S68 applications including X5M, X6M, XM, and the latest G90 and G99 M5 platforms, ensuring consistent performance and reliable fitment.
