Comparing decibels without looking at the standards is useless. Its perfectly possible to measure 50dB with one standard and 80dB with another on the same car.

This. Is the measurement taken at idle? Redline? A specific RPM? Is it a peak measurement taken when the car's revved to redline or a specific RPM -- and is that rev under load or while the car's at a standstill in park or neutral? And where is the measurement being taken: an inch from the exhaust? A foot? A meter? On axis (IOW, straight back from the bumper) or off axis?
Meaningless. Absolutely meaningless.
