The Akrapovič Slip-On Line (Titanium) (S-BM/T/40H) is a valved, rear-section exhaust for the BMW M3 (G80) and M4 (G82/G83). It replaces the factory mufflers with a lighter titanium system that adds power and torque, cuts 18.2 lb from the back of the car and gives the S58 engine a richer, deeper voice.

Performance and Sound

On the Akrapovič dyno, against a BMW M4 Competition with the stock exhaust, this system gained 10.7 hp at 6,000 rpm and 10.3 lb-ft at 5,000 rpm. No ECU remap is needed. Two valves and the matching Akrapovič control kit let the exhaust stay smooth and refined at cruise, then open into a deep, sporty tone when you drive harder, so one system covers daily driving and track days.

Materials and Construction

The system is made from high-grade titanium, and its collectors are cast in Akrapovič's own titanium foundry. At 33.7 lb it is about 35% lighter than the stock exhaust. The tailpipes, ordered separately, have hand-made carbon-fibre outer sleeves and come in Akrapovič's octagonal design or a classic round design.
