Active Autowerke Signature Rear Exhaust – BMW M3 Convertible (E93)

OVERVIEW

True performance, durability and attractive weight advantages, together with a set of genuinely innovative features, place the Active Autowerke E93 BMW M3 exhaust in a class of its own. Constructed from 100% 304 stainless steel, it uses adjustable Active Autowerke double-walled tips that also allow cleaner fitment alongside a diffuser. Factory-style flanges make it a complete bolt-on, while the straight-through design and large 3" piping substantially improve gas flow over the factory exhaust yet maintain enough back pressure to produce horsepower increases across the entire rev range. The sound is unobtrusive with a rich, mellow tone, and two Active Autowerke noise canceling chambers per muffler reduce the drone some mufflers emit at cruising speeds around 3,500 rpm.
