I tried one when I first got my bike powered 7 on the road.
I originally had a coby muffler - not quiet enough - over 111db at 5000rpm. test had to be at 5800!
put on a flow master hushpower - knocked sound down to 104db where I needed to get to 98db (94 + 4 for exhaust being within 1.5 metres)
eventually got sound to 98.2db (a pass) with a muffler from a radical. Since replaced with a larger ex-radical muffler so well within limits as long as I keeps the revs below 6000, which isn't often.

For an engine with slower exhaust gases e.g. 2 muffler on a v8 I think they work quite well. Replaced the rusty rear muffler on my old SAAB with the flowmaster which worked quite well.
