Description
Transform the exhaust sound of your BMW S68-powered vehicle with the MAD Catless Secondary Downpipes. Originally developed for the BMW X5M and X6M, these secondary downpipes are designed for enthusiasts looking for a deeper, louder, and more aggressive exhaust note while retaining the factory primary catalytic converters.
Unlike primary downpipes, secondary downpipes are installed further downstream in the exhaust system. This design allows you to enhance the exhaust sound without modifying the primary catalytic converters, helping avoid the check-engine-light concerns commonly associated with primary downpipe modifications.
Sound and Performance Benefits
The MAD Catless Secondary Downpipes provide a significant improvement in exhaust sound, producing a deeper, louder, and more aggressive tone that allows the BMW S68 V8 engine to sound more pronounced.
While secondary downpipes generally provide smaller power gains than primary downpipes, they can offer improved throttle response and a slight performance increase. For BMW X5M, X6M, X5, X6, X7, and XM owners looking for a balance of sound, performance, and reliability, these secondary downpipes provide a straightforward exhaust upgrade.
Premium MAD Construction
MAD Secondary Downpipes are manufactured from high-grade 304 stainless steel and feature precision TIG welding for durability and resistance to the extreme temperatures produced by high-performance BMW engines.
The direct bolt-on design makes installation straightforward and requires no cutting or permanent modification to the vehicle.
