Exhaust noise Db

Hi all,

 

Just wanted to share the results from my stock as a rock 03 noise test recently. I wanted to go to croft but the 88Db limit has everyone worried so I got the guys from TCE track day club to test mine.

 

Method: Sound level meter held down the centreline of the car, 1 meter away from the tip. Slowly increased the revs to 4300 (3/4 of max revs).

 

Result: 84Db @4300rpm

 

Its higher than I expected for a stock car but im happy. What kind of results is everyone else getting with different mods?
