Leo Vince cans are pretty. We like ’em. And they’re well built and work. Akrapovic are the benchmark, but these Leo cans with the carbon tips are good. The SMTs present no problem with an ECU remap – and this one was no exception. Once we’d sorted out the emissions equipment it was just a case of setting up the secondary butterfly valves, sorting the ignition maps and then adjusting the fuelling to suit.
