I called Jeff just to find out if the older LeoVince carbon exhaust would be in stock any time soon. Before I knew it, I was buying the LV-One based on his recommendation. (Truth be told, I wasn't 100% sure I was going to buy ANYTHING originally, but Jeff was so helpful, that I just had a great feeling about buying right away). I'm so very pleased with how well the exhaust sounds and feels. The installation was easy enough that I, with absolutely no motorcycle mechanic experience, was able to get them on in just over an hour. Great exhaust. Great price. I'm very impressed. Impressed enough that I'm going to go buy my next upgrade right now as a result :-)
