Aren't those Trumpet Mufflers really loud? I mean louder than any of the other aftermarkets?

Geez, at the price they are offering ($99US), they would be a great purchase but maybe not if they are too loud.

So is there a sound byte out there which we can hear and therefore determine if the trumpets are worth paying the big bucks for

Staintune Pipes, K&N Pods, 45 pilots, TBS needles and 145 mains.
