Looking to transform the sound of your 2024+ BMW X5M or X6M Competition without worrying about a check engine light? The MAD Catless Secondary Downpipes for the S68 engine are the perfect solution.
Why Choose Secondary Downpipes?
Unlike primary downpipes, the secondaries are installed further downstream in the exhaust system. This means you get the same aggressive exhaust tone and volume increase that most enthusiasts want, without interfering with the primary catalytic converters that trigger CEL warnings.
Sound and Performance Benefits
These downpipes are a customer favorite because they dramatically improve the exhaust note, adding a deeper and more aggressive tone that brings your S68 to life. While the power gains aren’t as large as with primaries, you’ll still notice improved throttle response and some extra performance. For many owners, this is the ideal balance of sound 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 deliver long-lasting durability. The bolt-on design makes installation straightforward with no cutting or permanent modifications needed.
