Hi Biker Dad,
Yeah, they sound awsome, and they are certianly louder than stock, but they have this awsome characteristic of being fairly tame on idle or steady throttle position, but they have an excellent crack to them when you get on the throttle. I think it is almost a perfect compromise. Also, they offer three baffles, quiet, standard, and performance. They swear that these do not alter performance, only volume. I have the standard, and one of my neighbours asked why my new pipes were so quite while is was idling in my drive. I blipped the throttle, and his eye went wide. I think he's going to get a set too
Good luck and tell Dusty at roadhouse that Chris in Canada sent you!
Cheers
