I live over in keighley but i lived in morecambe for years and my wifes family still live over there so we are up quite often, exhaust wise well mine was blowing so was more than likely down on power, but it really did perk up once the powerflow was fitted and even better once i took the cone filter off and refitted the standard airboxCheers mate.
