If you don't want loud, stay away from the HMF. Thats what i have and its very loud. My friend has a Pro-tec full system and it adds alot of power but has a decent sound thats not overbearing.

Take a look at Dr. D. Mine reads in at about 95 db and gave it a good dose of power throughout the rev range. Can't complain about it at all.

How about the FMF Q series of pipes. They make good power without hurting your ears.

I have the Yoshi/Suzuki stainless slip on. Bike runs great, sounds good, won't wake the dead. Down side???? A little pricey. $399.00 for just the slip-on.
