Akrapovic Exhaust System for BMW XM (G09)

This product is constructed from high-grade titanium, with integrated acoustic reflectors, designed to reflect the external sound toward the cabin and enhance the overall acoustic experience of the Akrapovic exhaust. Two integrated exhaust valves, each on one side of the muffler and operated by the Akrapovic control kit, tailor the gas flow for a rewarding sound experience. The sound has a linear flow based on the rpm and engine load, offering a smooth and harmonic tone at lower revs and rising to a distinctive V8 rumble in the mid-range before reaching a crescendo of high-frequency sporty sound when the revs rise higher.

The exhaust is finished with two sets of eye-catching tailpipes featuring a titanium inner sleeve and a hand-made carbon-fibre outer sleeve. The complex parts of this Slip-On Line (Titanium), including the valve housings and the two collectors, are all cast in the company’s in-house titanium foundry. The system is 11.35 kg (50.7%) lighter than the standard stock system.

It offers power and torque increases of 7.6 kW (10.3 hp) and 12.6 Nm, respectively, both at 5,750 rpm, when tested on the Akrapovic dyno against a BMW XM Label with an M exhaust system. The plug-and-play installation means no remapping is required, and it comes with EC/ECE type approval.

A further upgrade of the Slip-On Line (Titanium) system is available through the optional Evolution Link Pipe Set (Titanium)* aimed at those who want higher performance gains. Designed for exclusive track use only, installation of the Evolution Link Pipe Set (Titanium) means that the EC/ECE type approval for the Slip-On Line (Titanium) is no longer valid.

The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.

This product is designed to increase the performance potential of the Akrapovic Slip-On Line (Titanium) exhaust system. It is constructed from high-grade lightweight titanium. The system is 18.2 kg (63.5%) lighter than the standard stock exhaust. Installation removes the stock OPFs or secondary set of catalytic converters on non-OPF vehicles.

When combined with the Slip-On Line (Titanium), it offers power and torque gains of 25.8 kW (35.0 hp) and 47.7 Nm, respectively, both at 5,150 rpm, when tested on the Akrapovic dyno against a BMW XM Label with an M exhaust system. A special X-connection – cast in the in-house foundry – allows gases from both sides of the engine to mix for an enhanced sporty sound. 

For OPF vehicles remapping the ECU is mandatory to prevent potential check engine light warning signals. For non-OPF vehicles ECU remapping is not needed.

This part has been developed for use on closed-course competition circuits only. With the installation of the Evolution Link Pipe Set (Titanium), the EC/ECE type approval for the Slip-On Line (Titanium) is no longer valid.

THIS PRODUCT DOES NOT MEET THE EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller to regulate the valves.

With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
