Didnt read any of this thread but being on my third set of mufflers I like to think I have a bit of knowledge on this subject !
First set was the 49 state legal FRPP GT mufflers for the Mustang. Very loud and sounded really good until on the interstate. Too loud for hwy driving and the drone was terrible.
2nd set was the Shelby specfic mufflers ... basically a toned down version of the above ... less drone but still a drone and not nearly as loud.
....... and they say the third time is a charm ... got the KR mufflers and absolutly love them. Great sound at start up ... going through the gears ... no drone and very nice at interstate speed.
Also bought the H pipe but havent put it on yet
