Milltek Sport SSXBM931 Stainless Performance Exhaust for BMW M3 E90 4.0 V8

Give your E90-chassis M3 the sound and presence it deserves with the Milltek Sport SSXBM931 stainless performance system. Built in Britain from premium 304-grade steel, this direct-fit upgrade transforms the S65B40’s character with a richer, crisper note and improved flow, while keeping refinement on motorway journeys. It keeps factory catalytic converters in place, so you get the soundtrack and quality without compromising emissions equipment.

We run this setup on customer cars and it is consistently a favourite. Owners praise the clean fitment, refined cruising and addictive V8 bark when you lean on the throttle. If you want an OEM-plus look with a more purposeful tone and real longevity, this is the one to choose.
