Is it worth going the extra to an Aries "high performance" muffler over the stock? If any of you fine folks have the Aries "high performance" muffler, how much louder over stock is it?
Any recommendations for timing gear, since that seems to be a weak point that would logically be even more vulnerable with the increased hp?

So today I spoke with Jim? Joe? Davis, who
is Aries Mufflers, he had a seller booth at the Auburn (CA) Swap Meet (down from Oregon). I presented him with the scenarios above and asked his advice on whether a "high performance" muffler was indicated. He said no, the HP muffler is for engines 85 hp and above, and was aimed at the folks who did overhead valve conversions. He didn't think that the modest upgrades I planned in my Burtz would get there, and he advised against the HP muffler. Good enough for me.
BTW, he had one of his polished stainless mufflers on display. Boy is it gorgeous!
Thanks all who responded.
