Akrapovic Titanium Resonated Midpipe / Centre/Center Section OPF/GPF Delete Bypass for BMW G80 G82 M3/M3 Competition & M4/M4 Competition (2021+) — Evolution Link Pipe Set E-BM/T/12 | S58 Track Exhaust Upgrade

Akrapovic Titanium Centre Section for BMW G80 G82 S58 — Part No. E-BM/T/12

Transform the soundtrack and flow of your G-series M car with the Akrapovic titanium centre section designed to replace the factory particulate filter section for dedicated track use. Part number E-BM/T/12. This resonated midpipe in lightweight titanium is built to motorsport standards, freeing up back pressure, sharpening throttle response and unlocking the rich straight-six tone enthusiasts expect from the S58 while keeping refinement in the cabin.

Developed for vehicles equipped with OPF/GPF, this resonated mid section delivers proven results. On a BMW M4 Competition test car the setup recorded gains of +17.7 kW (24.1 hp) at 6,650 rpm and +25.4 Nm at 6,650 rpm versus the OE system, alongside an 8.4 kg weight saving. Pair it with the Akrapovic Slip-On Line in titanium for a deeper, fuller note without unwanted drone and an unmistakably premium finish.
