For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F90 M5 Collection, these S63TU downpipes represents our outlook on creating innovative products with performance in mind.

The S63TU downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory M5 downpipes – therefore reducing radiant heat and increasing performance. Our M5 downpipes will significantly increase horsepower and torque throughout the powerband. They will reduce any turbo lag

Our F90 M5 downpipes are manufactured in house using 304 stainless steel. Each set is meticulously tig welded and checked for perfect fitment. Our design uses a factory matched 3.5" v-band inlet that tapers to a high flowing, mandrel bent 3" body and includes the lower section sold by others as a "mid-pipe".

**Our downpipes allow the use of the OEM O2 sensor heat shield. With the heat shield installed the engine bay remains stock-looking for a sleeper look!
