akrapovic, not akripovic... I had one of those. In fact I had the leovince carbon and the akrapovic. Leovince sounds better. But akrapovic has a really high quality. I think you can't buy better quality. And it ran smoother than the leovince. Perhaps that is because the leo has a cat-eliminator. The akra hasn't.
The akrapovic is actually an exhaust for people who want the fz6 to be a little bit louder but not much. If you leave the db-killer in it sounds as loud as stock, but just slightly deeper. It actually sounded the way the fz6 should have sounded stock. If you take the db-killer out, then you have a really loud and deep sounding exhaust, slightly louder than the leovince with db-killer in. The leovince sounds really deep, even with db-killer in. Without db-killer it is extremely loud. Even with ear plugs I had my ears ringing after a ride. So I always rode with the db-killers in. But what I hated about the leovince was the fact that the bike didn't ran good. In fact I thought it had more on-off reaction. The akra was a lot smoother. With the akra I felt that it was good without the need to change ecu settings. With the leovince I constantly had the idea that it needed other ecu settings. Oh and the akrapovic is extremely light. I'm a perfectionist. That's the reason I sold the leovince and bought the akrapovic. And the akrapovic suited me like a glove.
