Evolution Line (Titanium)
The Evolution performance exhaust system for the BMW consists of a single-central muffler with valves and bigger link pipe tubes with a middle muffler, all designed to make the performance and workmanship of the Evolution as perfect as its looks. With no second set of cats (unlike the stock system), the whole system is designed to give the smoothest flow—and the power and torque gains of the BMW with the Evolution system are simply amazing. Crafted entirely from titanium, the Evolution system has a unique sound to complement its substantial increase over a very wide rpm range. In-depth engineering has produced a sound completely different from the stock system, giving a deep and sporty sound – with no unwanted overtones or drone, and also a significant change to the sound with the valves in the open or closed positions. The Evolution system needs no re-programming of the ECU because it doesn’t trigger any warning lights. With tailpipes in titanium or carbon, and a handcrafted rear diffuser, all available as optional extras, the BMW Evolution is as beautiful as it is powerful.
Slip-On Line (Titanium)
The latest addition to the BMW M series is the awe-inspiring M3/M4, an exquisite high-performance car that can be made even better by adding an Akrapovič Slip-On exhaust system. Made from titanium—with some parts cast in Akrapovič’s own foundry—it has bigger pipes than the stock exhaust, yielding lower back pressure and more power, especially at lower RPMs. This system is a completely new design, and it will reduce overall vehicle weight and deliver extra power and a sporty sound, which has been tailored to highlight lower frequencies and increase the listening enjoyment. Increases in both power and torque add to the sensory experience, combined with improved agility. The look of the Slip-On system can also be further enhanced by adding titanium or carbon- tailpipes and the stunning carbon- rear diffuser.
Downpipe (SS)
For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovič offers stainless steel, cat-less downpipes to make the BMW an even more powerful machine. This setup is intended for dedicated track-day cars and enthusiasts, and it will also add to the overall experience of what’s already a stunning performance car for any discerning driver.
Rear Carbon fiber diffuser
The Akrapovič Evolution and Slip-On line exhaust systems can be further enhanced with an optional hand-crafted carbon-fiber rear diffuser. Developed by Akrapovič’s R&D Department, this stunning diffuser, crafted from materials developed through Akrapovič’s racing involvement, is designed to perfectly fit the lines of the unique tailpipes of the Slip-On or Evolution systems, as well as complement the sleek and sporty shape of the BMW.
