I agree. Although Flowmasters have a wonderful sound, they tend to be kind of tiresome on the highways after a couple of hours. The Thrush mufflers are so nice and quiet when cruising, but open the throttle and they still sound very good. Plus you can't help but love the low price of Thrush turbo mufflers.
I've never tried the knock-off's, (i.e. Summit brand), prefering instead to spend 10 more bucks to get the original Thrush's.
