What kind of dB difference Will A silencer Make

[Jumanji]

Hey all, Looking at getting the skunk 2 megapower exhaust system soon and yes I have ready that it is a very loud system. I love the sound on it thought and am still keen on getting it anyone have any experience with what kind of dB it'll be pushing out (Have read a lot of articles online just wanted your opinions) Also what kind of dB difference will the silencer make on the exhaust?
Cheers

If you're gonna use a silencer, better to stay Stock exhaust.

No point

I know some guys that run silencers on the road and take them off on the track.

they make the car less droney and it sounds more raspy and louder with throttle opening instead of just all the time.

from what i have heard.
