MAD BMW 2024+ S68 Primary Catted Downpipes | G90 G99 M5, F95 F96 X5M/X6M & G05/G06/G07/G09

Description

Take your BMW S68-powered platform to the next level with the MAD Catted Primary Downpipes (MAD-162). Originally developed on the X5M and X6M, these downpipes are engineered for drivers seeking improved exhaust flow, stronger performance, and a more aggressive exhaust note while retaining catalytic converters.

Performance Benefits

The restrictive factory downpipes limit your S68’s potential. Upgrading to MAD catted downpipes improves exhaust flow, helping the turbos spool quicker and respond faster. The result is sharper throttle response, stronger midrange performance, and a more engaging driving experience while maintaining a more refined setup than catless downpipes.

Enhanced Driving Experience

MAD catted downpipes give the S68 a deeper, more purposeful exhaust tone without the full volume or raw character of a catless system. They provide an ideal balance for drivers who want a noticeable increase in sound and performance while retaining catalytic converters for improved exhaust odor control and a more street-friendly driving experience.

Precision Build

Each downpipe is constructed from thick 2.0mm 304 stainless steel, selected for its durability and resistance to extreme exhaust temperatures. Our TIG-welding and back-purging process delivers strong, consistent welds and smooth interior surfaces for unrestricted airflow.

Designed as a direct bolt-on upgrade, the downpipes use OEM-style brackets and flanges for straightforward installation and precise fitment.

Why Choose MAD?

Unlike generic alternatives, MAD catted downpipes are designed specifically for the BMW S68 platform, with fitment tested across multiple applications, including the X5M, X6M, and newer S68-powered vehicles such as the G90 and G99 M5.

Every set is backed by MAD’s limited lifetime warranty, giving you confidence in the construction, fitment, and long-term durability of your upgrade.
