I think it was 2003 when STB did their prototype for the Cobra on my car. They were the ones that measured my db at 104 at idle. After install of their product my db went down to 97 or 98, so they will quiet your car. On a side note, I lost a second and a half and 16 mph in the quarter. Needless to say, they are sitting on my shelf.
