Description
Looking to transform the sound of your BMW S68-powered platform without worrying about a check engine light? The MAD Catless Secondary Downpipes are the perfect solution.
Originally developed on the X5M and X6M, these are designed for enthusiasts who want a more aggressive sound across the latest generation of BMW V8 models—without the downsides of primary downpipes.
Why Choose Secondary Downpipes?
Unlike primary downpipes, the secondaries are installed further downstream in the exhaust system. This allows you to achieve a louder, more aggressive exhaust note without interfering with the primary catalytic converters, which are responsible for triggering check engine lights.
Sound and Performance Benefits
These downpipes are a customer favorite because they significantly enhance the exhaust note, adding a deeper, more aggressive tone that really brings the S68 to life.
While power gains aren’t as large as with primary downpipes, you’ll still notice improved throttle response and a slight bump in performance. For many owners, this is the perfect balance between sound, performance, and reliability.
Premium MAD Quality
Built from high-grade 304 stainless steel with precision TIG welding, the MAD secondary downpipes are designed to handle extreme heat and provide long-term durability.
The direct bolt-on design makes installation straightforward, with no cutting or permanent modifications required.
Why Choose MAD?
Unlike generic options, MAD secondary downpipes are designed specifically for the S68 platform, with fitment tested across multiple models including the X5M, X6M, and newer S68 vehicles like the G90/G99 M5.
Backed by our limited lifetime warranty, this is a simple upgrade that delivers big results.
