Premium performance exhaust upgrade for BMW X3 M F97

Unlock a ferocious soundtrack and sharper throttle response on your BMW X3 M with this Austrian-built performance rear system. Engineered for the S58B30A 3.0 twin turbo platform, this valved sports exhaust delivers a deep, motorsport-inspired note with refined manners when cruising, thanks to full compatibility with the factory valve control. Quad 102 mm carbon fibre outlets with titanium inners complete the look with a purposeful, high-end finish.
