Its strange that people think Termi are quieter than Termis :-\
I was at some traffic lights and a ducati S2R pulled up beside me that had Termi's on it. He started reving his engine and so did I, he actually turned and looked at me nodding to show he was impressed. My exhausts were obviously louder than his, there was no question about that. Perhaps its because I have taken the silencer/muffler/DB Killer part out of my cans *shrugs*
Edit:
I have just put the DBKillers back into my bikes cans.. its made one hell of a difference!! It is alot quiter now... not too keen on it now.. but without them was actually giving me ear ache!! So its best to leave those in I think.
And like above, without them I have actually set a few car alarms off ROFL that was funny LOL but a bad thing was little dogs usually ran out infront of me barking at me... I have almost hit several dogs, cats are smart enough to run, but dogs??? So having the DBKillers back in is my best option.
