Exhaust Akrapovic Slip-On BMW 4 COUPE M4 353KW 01-21

Finished with hand-crafted carbon fiber tailpipes, this high-grade lightweight titanium system weighs 35% less than stock and features a pair of in-house foundry cast headers. The Slip-On (Titanium) comes with a specially developed Akrapovic control kit for a complete sound experience. The sound offers a rich tone during normal cruising, transitioning to a deep sporty tone when the M3/M4 is driven more dynamically. The system offers a perfect sound at all revs, merging comfort and sportiness in a single exhaust. For the mufflers there is a choice between those featuring a revolutionary octagonal shape molded from lightweight titanium with a carbon fiber outer sleeve or those featuring a classic cylindrical design, perfect for more traditional buyers. The system offers power increases of 8.0 kW (10.9 hp) at 6,000 rpm and a torque gain of 13.9 Nm at 5,000 rpm, data obtained on the Akrapovic dyno with a BMW M4 Competition with stock exhaust. Remapping is not required for this setup and fits all vehicles (OPF and non-OPF), but the ECE certificate is only valid for cars fitted with an OPF filter. Optional header pipes are available for customers wishing to change the exhaust for closed loop use. An optional Akrapovic Sound Kit is also available. With the installation of the optional connecting pipes, the donw-pipes and the Akrapovic Sound Kit, the ECE homologation of the Slip-On (Titanium) is no longer valid. An optional handcrafted carbon fiber rear diffuser is also available to add further visual impact to the Akrapovic tailpipes. The system is also suitable for xDrive models. The Slip-On (Titanium) exhaust system is ECE approved for cars equipped with an Otto/petrol particulate filter. Terminal set must be ordered separately as a mandatory part. Please choose TP-CT/69 or TP-CT/68.
