Any sound meters set "SLOW" on weighing "A" human ears vs "C" setting will be a lot higher.

I haven't looked too carefully into the muffler- / exhaust-related sections of the MVA yet, but here is what a short section of it says:
Quote:
Section 7.03(4) -- Muffler - Alteration prohibited
No person shall drive or operate a motor vehicle propelled by an internal combustion engine equipped with a muffler the exhaust outlet of which has been opened or widened.
Section 7.03(5) -- Noise increase or flames prohibited
No person shall drive or operate a motor vehicle propelled by an internal combustion engine equipped with a muffler or exhaust system to which is attached any device which increases the noise of the expulsion of the gases from the engine or allows a flame to be emitted from the exhaust system.

I find the wording of these two sections to be rather vague and open to "interpretations" -- perhaps this is done intentionally so to allow some "flexibility" when the MVA is enforced.
If Carguru can point me to the sections where there is supporting evidence of "From the tip to the canister has to be the same diameter. Under 3"", I would greatly appreicate it.
