Silencer for M4 Street Slayer?

[TheWhiteSamoan]

Are there any silencers I can buy in addition to the stock silencer that comes in the M4 Street Slayer Carbon exhaust? I am getting the exhaust primarily because it looks better than stock, but it's a bit on the LOUD side. So I was wondering if there is any way I could further "muffle" the sound.

I'm looking to get the same exhaust. Best looking in my opinion. The do come with a removable silencer I believe. Anyone have any outside sound clips or ride by?

Someone wrapped the silencer in steel wool to make it better. Thread for reference.
