Sounds like they are uneven across their product line, or have been in the past, but I think it's safe to say that this particular product (the 2005 Mustang GT axle-backs) is about as good as it gets...

That said, the FRPPs are also top-notch, made by Borla, and they get rave reviews.

When I do axle-backs, I too, will likely be choosing between these two.

Macs seem to have more of a "tuned" exhaust note, very baritone, and people seem to love it. The FRPPs seem even deeper, but somehow more natural sounding. The drone feedback for both has been mixed up enough that I really don' know what to expect until whichever one I buy gets installed, and I actually drive it my own self...

Anybody have a linky to some good sound clips for the mac's and the frpp...Thanks

There are a ton of links. Search these and other mustang forums. A few of the forums have sticky exhaust threads with many clips. Have fun.

sound sweet few questions, first off please tell us that the car was warm when you got in a revved (if not that poor motor), and second why is there only "fog" from the drivers side tip??? thanks, this isn't an attack just curious!

I hope that wasn't a serious question. Of course it was warmed up.

There actually is "fog" coming out of the passenger side exhaust, but it is in the shade and it's hard to see since it was really sunny out (I know, hard to believe the sun was out in Michigan during the winter).
