Upgrade from the stock S63R downpipes to the MAD S63R Catless Downpipes for your X5M or X6M — built for maximum airflow, power and sound. Replacing the restrictive factory downpipe wakes up the S63 with a more aggressive note and sharper throttle response.

Crafted from premium stainless steel with a mandrel-bent design, they keep exhaust gases flowing smoothly for optimised performance and more horsepower and torque. Engineered as a direct replacement, they bolt on cleanly and work with a wide range of aftermarket exhaust systems and tunes.

Features

• Catless design for maximum exhaust flow.
• Premium mandrel-bent stainless steel construction.
• Compatible with right- and left-hand-drive vehicles.
• Smooth bends for maximum airflow with no drone, plus a flex section.
• Up to 30 HP on stock turbos — even more with upgraded turbos.
• Lifetime warranty on defects and fitment; 90-day return; ships in 1–2 business days; spot-on fitment.
