      Titanium link pipe set with resonators
      Titanium X-pipe
      Titanium muffler with integrated exhaust valves
      Hard facts:

      Plus 11 HP (at 6,200 rpm)
      Plus 15 Nm/11 lbs-ft of torque (at 2,270 rpm)
      23 kg/51 lbs. lighter than stock

        nice....I always like they offer dyno #s right away and are straight forward with their #...never claim insane numbers...even on their full systems show the low end power loss. They just seem like a straight forward company. I think they should offer stainless steel versions for the people who arent willing to spend an arm and a leg on an exhaust

        Their numbers are realistic, I like that. Just wondering what is with that torque dip at 2500 rpm.

        I would think they will do a steel version, they do for other cars right?

        yes, and they really shine in motorcycle category. maybe Devil exhaust is the better choice for S1000RR but that's just it. overall Akrapovic makes me the best exhaust system for motorcycles

        It looks nice. Although I was not impressed with the exhaust on the E92 M3 and the way it sounds.

        I had it and AGREE about the sound. Boring sound, not inspiring compared to other exhausts out there. But the good thing is that it isnt loud and having a SC'd car it help keep it on the down low. My eisenman race muffler sounded louder and better than my full akra evo

        You right, the quality is excellent. But the aural part is missing something. You don't want to sound like an unrestricted race car but more sexy than stock. Looks the part, but missing sounds to my ear.

        maybe that doesn't work for you guys , but with Eisenmann race i recieved many tickets for having a loud exhaust system , i think i could live better with Akra exhaust.

        The Eisenmann Race Exhaust is that loud? They usually have 2-3 exhausts depending on driver exhaust tolerance.

        full race exhaust is considered as a loud exhaust to officers here
