Active Autowerke Race Downpipes – BMW M5 (F90)

OVERVIEW

For over 30 years Active Autowerke has been the name to turn to for high quality BMW performance products, and these S63TU downpipes are the newest addition to their F90 M5 collection. They are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory M5 downpipes, reducing radiant heat and delivering a significant increase in horsepower and torque throughout the powerband along with reduced turbo lag and a more aggressive exhaust note. Each set is manufactured in house from 304 stainless steel, meticulously TIG welded and checked for perfect fitment, and accepts the OEM O2 sensor heat shield so the engine bay remains stock-looking for a sleeper build.
