Constructed from high-grade lightweight titanium with two pairs of titanium / carbon-fibre tailpipes and featuring exhaust valves with housings cast in the in-house foundry, the Akrapovič exhaust system for X4 M/ Competition is a stunning design that combines performance with an incredible soundtrack and huge visual appeal. The sound has been tuned to ideally suit the in-line six-cylinder turbo engine, delivering an increase in the volume sensation, which provides exciting acoustic feedback when shifting through the gears. Any unwanted drone is eliminated. The optional Akrapovič Sound Kit can be added to upgrade the package.
An upgrade for the Slip-On Line (Titanium) system, the link pipe set is constructed completely from high-grade titanium and provides further aural experiences from a sound spectrum perfectly matched to the car’s in-line six-cylinder turbo engine. The sporty nature of the engine is balanced out to deliver a true racing sound without any unwanted cabin drone. An individually designed and developed link pipe section that blends the exhaust pulses from each turbocharger allows Akrapovič to add its deep signature sound to the car harmoniously all the way to the engine’s red line – all without compromise on comfort.
When installing the Akrapovič Evolution link pipe set, remapping the ECU is mandatory in order to prevent potential “check engine light” warning signals.
