Thanks for the reply. I guess that my garage rates a solid "B" on soundproofing. I put rigid foam between the studs, a layer of 5/8" wall board, new windows, and triple layer 1.5" thick steel garage doors.
I should have been more clear. Since I cannot run the engine for long inside a closed garage, I was thinking of building some sort of external muffled box or tubes to fit over the exhaust exits to limit the sound to a reasonable level.
