CTS TURBO CATLESS 4″ DOWNPIPE BMW N55 (ELECTRIC WASTEGATE) X4 M40I -CTS-EXH-DP-0023-M40i

With two flawlessly styled and finished handmade carbon-fibre tailpipes, which beautifully complement the titanium pipes, this exhaust is a work of art. It comes complete with a soundtrack that perfectly matches the car’s performance, ideally tuned to produce a unique sound colour and the celebrated Akrapovič signature sound.

UNPARALLELED R&D

From the R&D department with sound engineering—and through the laboratories that manage and measure the materials and into the in-house titanium foundry and then to production, before evaluation and completion—the manufacture of an Akrapovič exhaust is an internal journey with many facets that are all completed at the company’s state-of-the-art facilities.

ONLY HIGH-TECH MATERIALS

Using only the highest standard of materials in the production of every Akrapovič exhaust, our materials are thoroughly inspected upon arrival and assessed in the metallurgical laboratory. Though more than 30 years of experience working with titanium, stainless steel, carbon fibre, aluminium alloys, and more recently ceramics matrix composites, Akrapovič sources only the best materials to produce its high-quality exhaust systems.
