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 Slip-On Line 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. Fully ECE-compliant, the Slip-On Line (Titanium) provides power and torque increases over the BMW SUV with the stock M Sport exhaust system throughout the entire rev range, as measured by Akrapovic’s skilled engineers. The use of state-of-the art materials reduces the weight by 10.7 kg compared to the M Sport exhaust. The optional Evolution Link pipe set (Titanium) and an Akrapovic Sound Kit can be added to upgrade the package. When fitted with the optional Evolution Link pipe set (Titanium) and Akrapovic Sound Kit, ECE type approval is no longer valid. An optional high-gloss rear carbon-fibre diffuser is also available to provide a distinctive finishing touch.
Tail pipe set (Carbon) has to be ordered separately as a mandatory part. Please choose TP-CT/60 for X4 M / Competition model.
For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.
