RE: Is noise really the problem....?
Folks............................the laws around here governing noise are not subjective. There are specific decibel levels that you may not exceed at the edge of your property.
Most mufflers are rated at 90db at 3 meters.
The decibel level drops off rapidly with distance. Find out what the legal limit is in your area and check the noise level at your property line.
Its easy to do.
