js racing


depends which one and what your running for example i have a 60rs with 5zigen header and feels cat 95/96db hope this helps
 
If you're already running it then get hold of a db meter and measure it?

Also "what db is it" is a vague question, you want to know db at idle? WOT? the usual 2/3 revs testing for track days? flyby?

Not trying to take the piss, just a bit more info to posts goes a long way :thanks:
