do exhaust silencers really work?

[jigs]

just installed apex'i gt on a ka motor. it is too loud.
what do you think about these silencers in the market?

like these:

and these:
Apexi 155-A025 Active Tail Silencer 115mm for GT Spec & N1 Turbo (http://www.frsport.com/Apexi-155-A025-Active-Tail-Silencer-115mm-for-GT-Spec---N1-Turbo_p_8062.html)

Silencer's helpped my brother little eg6 with a APEXi exhaust that had a really nice deep tone not the annoying ricer tone but he still got crap from the cops since it was a honda with an exhaust and they always followed him after he passed them.

And after he put the silencer on, it cut the sound by half or more cuz he stoped getting harrased by the cops that always follwed him.

So I would reccomend one if you need to tone it down.
