AKRAPOVIČ EXHAUST SYSTEMS

Akrapovič, the benchmark in the exhaust manufacturing industry. The brand is synonymous with the highest level of design, performance enhancement and the creation of an unmistakable deeply resonant exhaust sound. Akrapovič products are designed and manufactured for performance vehicles by a passionate and highly-skilled workforce of over 800 employees using the latest technology, processes and finest materials. The Racing R&D department works with dozens of racing teams with over 90 world championships.



The latest addition to the BMW M series is the awe-inspiring M3/M4. Made from titanium—with some parts cast in Akrapovič’s own foundry—it has larger diameter pipes compared to 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 your 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.

AKRAPOVIČ EXHAUST SYSTEMS

Evolution Link Pipe Set

The Evolution link pipe set upgrades the Slip-On system to the Evolution system, which consists of a single-central muffler with valves and bigger Evolution link pipe tubes with a middle muffler, all designed to make the performance and workmanship of the complete system as perfect as it looks. With no secondary cats the whole system is designed to give the smoothest flow. Power and torque gains for the F80/F82 M3 and M4 with the Evolution link pipe set in combination with the Slip-On system are absolutely guaranteed. Crafted entirely from titanium, the complete system has a unique sound to complement its substantial increase in power and torque over a very wide rpm range. In-depth engineering has produced a sound distinctly 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 complete 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 with the Slip-On Line and Evolution link pipe set is as beautiful as it is powerful.

Downpipe

For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovič offers stainless steel, cat-less downpipes to make your BMW an even more exciting machine. This setup is intended for dedicated track-day cars and enthusiasts, and it will also add to the overall experience of what is already a stunning performance car for any discerning driver. Delivering great sound, without creating unwanted cabin noise, these beautifully-crafted downpipes offer an upgrade to Akrapovič’s Evolution exhaust system.

When installing Akrapovič aftermarket optional down pipes , which are developed for use on closed tracks only, remapping the ECU is mandatory or optional Delete-R has to be installed, in order to prevent potential »check engine light« warning signals.








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 Design 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.

Can't wait to shoot it again soon

Akra is deff a top quality exhaust company for sure.
But not the best in my and many other opinions for the S55 engines.
The Akra needs the cats removed to really make the system sound great.

If akra ran a single mid-pipe it would sound so much better. No doubting its quality but the sound is nowhere near as good as some of the other offerings on the market.

I never heard the Akra in person, but either way, excited as hell to put it on. I even thought the stock exhaust sounded pretty decent, im sure this will be a step up

For sure, I'll try to get some video and clear audio also, although they never really do the exhausts justice!

Everyone who has the Akra seems to love it. Although I went with the AA, the Akra was really tempting. I think without a doubt, it is the most well-made system out there and it is also the lightest, which is a huge plus. It was a tough decision for me - I wish there was a combination of light weight and perfect sound, but there are always tradeoffs. I have nothing but full respect for the Akra system and I can't knock it in any way. It is beautiful to look at and the craftsmanship?... damn... it just looks so flawlessly made. I can see why people choose this system.
