F10 F12 M5 M6 DOWNPIPES

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 F10 F12 M5 M6 Collection, these S63TU downpipes, is a true testament to 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 and M6 downpipes – therefore reducing radiant heat and increasing performance. Our M5/M6 downpipes will significantly increase horsepower and torque throughout the powerband. They will reduce any turbo lag

Our M5 and M6 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.

**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!
