Slovenian aftermarket vendor Akrapovič has expanded its offer with a titanium exhaust system and a carbon-fiber rear diffuser for the BMW M3 (G80) and M4 (G82), landing both with performance improvements from just those two mods.
The exhaust comes manufactured from titanium and features an active valve to enable fine adjustment of its soundtrack. Note the unexpectedly cool-looking octagonal quad tailpipes: their shape mirrors that of the grille and looks like a perfect fit on a latest-gen BMW vehicle. Then again, classic round finishers are also available if you would rather have those.
Interestingly enough, the exhaust alone raises the power of both cars by up to 10.9 horsepower (8 kilowatts) and the torque by up to 13.9 Newton-meters (10.3 lb-ft). The announcement emphasizes that no software modifications were performed and no filters removed, making the upgrade fully road-friendly.
