It was great the first few days, but the high pitched rev suddenly annoyed me and so I thought I'd do something about it. It sounded like a mini version of Cicero's, but it suited his 600 well compared to my 400. The short rear pipes were the culprit, sounding more like bubbles underwater. Since the old stocks were just lying around in the garage I hacked it on both ends and attached it to the ends of the new pipes, but all it needed was the rear exhaust being serviced by the 4mm pipe inside the stock and the familiar growl returned. The thicker stock also made the puddle flow better than the thinner ones. Ending with elbow bends blowing sideways, damn nice.Another afternoon well spent.
