Akrapovic Titanium Rear Section for BMW F30 F31 F32 F33 F36 340i 440i with OPF/GPF

Elevate the sound, response and look of your B58-powered BMW with this premium titanium rear silencer from Akrapovic. Crafted from lightweight titanium with beautiful carbon fibre tailpipe finishers, this valve-controlled rear section brings a deeper, more characterful tone, crisp throttle feel and meaningful weight reduction on OPF or GPF equipped cars while remaining EU type approved for the road.

We have installed this system in-house and our customers absolutely love the transformation. At light throttle it is refined and sophisticated. Press on and it opens up with a rich, motorsport-inspired note that suits the 3.0 turbo six perfectly. It keeps the daily comfort you want and adds the excitement you buy a performance BMW for.
