Mufflers - Incredible Difference!
I just replaced a set of high dollar, switchable mufflers to a set of IMCO Gattling Gun type. Wow, what a difference. The sound level inside the boat as well as out is at least 50% better if not more. Zero back pressure, no black on the transom and best of all no fouled plugs. The best single improvement I've ever performed on any boat...
