Anyone know how loud the full exhaust is? Decibels?

Thinking I might have to use the noise reducer for my own sanity.

Stock exhaust:
Idle / 5000rp
79 dbA / 89 dbA


Thanks :)

got a 2 bros.full system and got the 2 power tips they offer for them one reduces noise by 4to 5 d.other 7to 8 d.i i like the 8 better,dont like the noise on longer trips.i got both tips because of price 25.00 and 30.00.easy to switch out.if your after less noise they both get the job done the 8 is better for me.my advice,get both. lets ride....

Didn't think the stocks measured that loud. My cruiser's stock pipes were only measured to be 76dB from 5' @ 4k RPMs and 30dB from 5' @ idle. The 300 seems quieter than the cruiser. Although things are much different I guess when you on the bike and when you're behind the bike.
