Years ago when we used to do Thursday night meets at ironwoods, a couple rcmp showed us how they do it. Pretty much hold the meter one metre away, then side step 45°, then raise it one metre above the ground, and hold your rpm 50% of the beginning of redline
This is *not* how they describe it in whatever laws someone will quote, this is just what the rcmp demonstrated

So what is the actual law in proper method for testing exhaust db?
