Oh boy, here we go again.
I had short TOR's on my bike too for a very short time. I felt they were just too quiet and lacked the toughness I wanted in the sound. As many threads here have showed: this comes down to taste and what is quiet to me, might be loud to you. That being said...I switched to EPCO's and I'm very pleased. Much more growl and a LOT more volume. These are still kind of 'neighborhood friendly' too if that is important to you.
