As for performance, we tested the LeoVince against the stock exhaust on the same dynamometer and saw significant gains. Where the stocker made 127.3 peak horsepower at 12,750 rpm, the aftermarket pipe, working with a preprogrammed Dynojet Power Commander, boosted that to 131.55 bhp at 13,500. That made for a noticeable improvement, not just in the sheer quantity of power but also by giving the bike the additional revs to save an upshift and downshift on some straightaways. The torque figures didn't change quite as dramatically, but what the graph did show was a smoother curve. Throttle response also was much crisper.
