The Idle still sounds nice even with the slight rasp, but it is pretty raspy at just off idle but, at about 1,500 maby ( no tach ) it starts to clean up and sound nice. You could try a set of Turbo Mufflers, Summit's got cheap 1's for 14.99, they might not be as raspy. I'm putting fenton cast iron headders on mine, with smitthys mufflers and echo can tips ( period correct parts, still produced ) it will be all 2"
