🔥 MAD S63R Catless Downpipes – Maximum Flow, Maximum Power

Take your S63-powered BMW to the next level with the MAD S63R Catless Downpipes. Designed for enthusiasts who demand peak performance, this high-flow exhaust upgrade eliminates factory restrictions to deliver serious gains in horsepower, torque, and exhaust sound.

Whether you're chasing track times or just want to unleash that deep, aggressive exhaust tone, MAD’s catless downpipes are the upgrade your F95 X5M or F96 X6M needs.

💪 Built for Performance

Crafted from T304 stainless steel, the MAD S63R Catless Downpipes are built to handle extreme heat and abuse while delivering superior exhaust gas flow. The mandrel-bent design eliminates bottlenecks and turbulence, optimizing your turbo’s efficiency for faster spool and increased power.

By removing the restrictive factory catalytic converters, you’ll unlock up to +30 horsepower on stock turbos—and even more with upgraded setups.

🔊 Aggressive Sound, Zero Drone

The catless design not only boosts performance, but also enhances your S63’s sound profile. Expect a deeper, more aggressive exhaust note, with no drone inside the cabin thanks to smooth piping transitions and an integrated flex section for vibration control.
