BusterW ... I totally agree. I put that power core in & as we all know, they are loud ..... slipped the Benz muffler on & Holy Crap .... now that's quiet.
I need to get a sound clip of the difference (if I can figure out to post'em here or on photobucket or where ever ...) for everyone to hear.
I was just surprised it "Slowed" the motor down. (According to that tach as well as my "tuned ear" ... WHAT ??)
I'm sure I'm gonna run it, once I figure out how to mount it with all the other crap I have at the rear of my machine ..... Jeez !
Later ...
