Active Autowerke S63TU Downpipes for BMW F90 M5

For over 30 years, Active Autowerke has been the go-to name for high-quality performance upgrades for BMWs. Their latest release, the S63TU downpipes, is designed specifically for the BMW F90 M5 (2018-2022), and it's a game changer for those looking to maximize their ride's performance.

Performance Enhancement

These downpipes are meticulously engineered to eliminate the restrictive nature of the factory M5 downpipes. By doing so, they significantly reduce radiant heat, allowing for a noticeable increase in horsepower and torque across the powerband. If you’re tired of turbo lag, the S63TU downpipes are here to help you spool up faster and get the most out of your engine.

Quality Construction

Manufactured in-house using durable 304 stainless steel, each set of downpipes is TIG welded for a precise fit. The design features a factory-matched 3.5" V-band inlet that tapers into a high-flow, mandrel-bent body, ensuring optimal exhaust flow. Additionally, the lower section of the downpipe is included, which is often sold separately by other brands.
