ACM Exhaust Mod

Would anyone know the DB level of an ACM exhaust mod (everything else stock)?

Some local tracks (Circuit Mont Tremblant) have DB level restrictions.

thanks

Take your muffler off, buy a cheap sound level meter, measure and it should be pretty close.

Our Oem. (stock) exhaust full trottle = 90 DB

After (with) Oem. exhaust mod. full trottle = 93-94 DB

Eisenmann/Race exhaust full trottle = 99 DB

I'd be interested in knowing too. I'm think about this exact setup and would love to hear it too if you pull the trigger.
