Mivv have often been the topic of conversation on here for various bikes, some have found the quality satisfactory and some (me included) have not which is what you would expect. Mivv as a company have been around for a while but IME, have tended to cater for the budget end of the motorcycle exhaust business. Like Arrow, you don’t get anything else in the box so if you want exhaust valve eliminators or ecu gizmos to minimise a lean mix, you’ll have to look and pay elsewhere. Andy
