I love my Akra! The sound is very intoxicating and exotic, it is pretty quiet when cruising, but under hard acceleration is where the Akra comes alive. I get so many peeps turning head wondering what's making that sound. Check out this Youtube clip, this is one of my favorite video of the Akra.
I was going to get the Eisenmann Race, but wanted a full exhaust instead of a section 3. Since the Full Eisenmann Race price was pretty much close to the Akra, I chose the Akra. It is full titanium, plus no one else makes carbon tips, quality is superb, second to none!
