Has anyone ever seen this article from Anderson Ford Motorsport before?

The sound difference at idle, stock vs. no mufflers, is said to be 5 decibels. Others like the FRPP Stingers, I think was 4 decibels. It doesn't sound like much, so maybe 4 decibels is really a lot or there is an illusion of being much louder.

i dunno about that.....must be one heck on an illusion

I checked an occupational health and safety text book I have and a 2 decibel increase is said to be noticeably louder, so the ones that are 4-5 decible louder than stock are two levels of loudness above stock and that's just at idle.

I wonder how many decibles I'm at..I can set off car alarms in parking garages... [/align]

Probably over 100 db when you rev.

Tell me about it, I'm a habitual alarm setter-offer

Correct me if I'm wrong, but I think adding 3 decibels = twice as loud, so that's a pretty big difference haha

157dB

3dBs is perceived as twice as loud.
