EXHAUST UPGRADES
BMW M3 / M4 (G80,G81,G82)
As the UK’s largest Akrapovič dealers, Litchfield are pleased to be able to offer both the Titanium Slip-on system and the Evolution Line system for the BMW M3 (G80) and M4 (G82). These are manufactured using their world renowned Akrapovič proprietary heat resistant titanium alloy offering power gains and impressive weight reductions.
Akrapovič exhausts feature an unrivalled level of attention to detail and intelligent design. These represent the very best exhaust upgrades on the market.
Akrapovič offer their Carbon and Titanium tail trims in two different designs; a subtle classic cylindrical design or ground-breaking octagonal shape which is in keeping with the aggressive lines of the car.
The Akrapovič exhaust starts with their Titanium Slip-On (axle back) exhaust system for £6,968 inc. VAT and provides an 11 bhp improvement in power and reduces weight by 8.3kg.

Standard Mandatory Carbon Tail Trims
Optional Octagonal Carbon Tail Trims
This high-grade lightweight titanium system, finished with hand-crafted carbon-fibre tailpipes, weighs in at 35% lighter than stock and features a pair of collectors cast in the in-house foundry. The Slip-On Line (Titanium) comes with a specially developed Akrapovič control kit for a complete sound experience. The sound character offers a rich tone at normal cruising, rising to a deep sporty sound when the M3/M4 is driven more dynamically. It serves up a perfect sound at all rpms, delivering comfort and sportiness in one exhaust. A ground-breaking octagonal shape has been fashioned from lightweight titanium with a carbon-fibre outer sleeve for the tailpipes, and for more traditional buyers there is the classic cylindrical design.
The system delivers 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 when tested on the Akrapovič dyno against a BMW M4 Competition with a standard stock exhaust. Remapping is not needed for this configuration, and it fits all vehicles (OPF and non-OPF), but the ECE certificate is valid only for cars equipped with an OPF filter.
Optional link pipes and downpipes are available for customers looking to change the exhaust for closed circuit usage. An optional Akrapovič Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovič Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid. An optional hand-crafted carbon-fibre rear diffuser is also available to add an extra visual impact to the Akrapovič tailpipes.
The exhaust system also fits xDrive and M4 (G83) Convertible models.
The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.

The link pipe delivers a power gain of 24 hp at 6,650 rpm and torque increases of 25.4 Nm at 6,650 rpm when tested on the Akrapovič dyno against a BMW M4 Competition (OPF/GPF) with a standard stock exhaust. Combined with a Slip-On Line (Titanium) delivering a deep, rich, and sporty sound without drone, it totally embraces the pure turbocharged inline six-cylinder sound.
