Akrapovič BMW M3/M4 (G80/G81/G82/G83) Slip-On Line Titanium Exhaust System

The Akrapovič Slip-On Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the G80/G81 M3 and G82/G83 M4. Crafted entirely from lightweight titanium, this system is designed to enhance every aspect of the driving experience, from sound and performance to weight savings and aesthetics. More than just an exhaust, it's the finishing touch the M3/M4 deserves, how it should have come from the factory.

The Slip-On Line transforms the exhaust note entirely, delivering a smooth, refined tone at cruising speeds that opens up into a deeper, more aggressive growl under acceleration, perfectly complementing the car's sporty nature. A specially developed Akrapovič control kit lets you tailor this sound character, rich and comfortable at normal cruising, rising to a genuinely deep, sporty character when driven more dynamically. The freer-flowing design reduces backpressure, improving gas flow and letting the engine respond more efficiently. Independent dyno testing confirmed genuine gains of 8.0kW (10.9hp) at 6,000rpm and 13.9Nm of torque at 5,000rpm, alongside a substantial 35% weight reduction (8.3kg lighter) than stock, all without requiring any ECU remapping.

Finished with hand-crafted carbon-fibre tailpipes, available in either a ground-breaking octagonal shape (titanium with a carbon-fibre outer sleeve) or the classic cylindrical design, both included as part of this system.

Please select your tailpipe style at checkout: Octagonal or Cylindrical (Round), included as part of this purchase.

Fits both OPF and non-OPF vehicles, though ECE type approval is only valid when installed on cars equipped with an OPF/GPF filter.

Optional upgrades available: the Evolution Link Pipe Set (available in titanium or stainless steel) and an Akrapovič Sound Kit are available for closed-circuit use, though installing either invalidates ECE type approval. A hand-crafted carbon fibre rear diffuser is also available in gloss, gloss black, or matte for additional visual impact.
