Description
Upgrade your BMW S68-powered vehicle with the MAD Catted Primary Downpipes (MAD-162), engineered to improve exhaust flow, enhance turbocharger response, and deliver a deeper, more aggressive exhaust sound while retaining catalytic converters. Originally developed for the BMW X5 M and X6 M platforms, these high-flow catted downpipes are designed for a range of S68-equipped BMW vehicles, including the G90 and G99 M5, F95 and F96 X5 M and X6 M, and compatible G05, G06, G07, and G09 models.
The MAD S68 primary downpipes offer a performance-oriented upgrade for drivers seeking improved exhaust efficiency, sharper throttle response, and a more engaging driving experience.
Performance and Driving Benefits
Factory downpipes can restrict exhaust flow and limit the performance potential of the S68 engine. The MAD high-flow catted primary downpipes are designed to reduce this restriction, helping the turbochargers spool more quickly and respond more effectively.
Key performance and driving benefits include:
-
Improved exhaust flow and enhanced performance potential.
-
Faster turbocharger spool and sharper throttle response.
-
Stronger midrange performance and improved engine responsiveness.
-
A deeper, more purposeful exhaust tone with a more aggressive character.
-
A more refined sound profile compared with a catless downpipe configuration.
-
Retained catalytic converters for exhaust odor control compared with catless setups.
Actual performance, sound, and emissions-related results may vary depending on the vehicle, tuning, exhaust configuration, and other supporting modifications.
Premium Construction and Precision Engineering
Manufactured from heavy-duty 2.0mm-wall 304 stainless steel, the MAD downpipes are designed to withstand demanding exhaust temperatures while providing durability and corrosion resistance.
Each set features TIG-welded construction with back-purging to support strong, consistent welds and smooth internal surfaces. OEM-style brackets and flanges are incorporated into the design to provide a direct bolt-on installation approach and precise vehicle fitment for compatible applications.
Why Choose MAD Catted Downpipes?
Developed specifically for the BMW S68 platform, the MAD-162 downpipes are designed with applications including the X5 M, X6 M, and newer G90 and G99 M5 models in mind. Their high-flow catted design combines performance-focused exhaust flow with catalytic converters for drivers who want a more aggressive exhaust setup without choosing a completely catless configuration.
Each set is backed by MAD's limited lifetime warranty, subject to the manufacturer's applicable warranty terms.
