I just picked up a 93 GT. I have a question regarding exhaust. Currently the car has Full 2 1/2" exhaust w/ MAC flowpath mufflers. The drone from these mufflers is incredibly loud. What muffler would you all reccommend to be the quietest without sacrificing power. I am not looking to wake up the neighborhood, and I would like to be able to hold a conversation while I am driving.... Here is the full list of mods and a couple pics...

I've also heard good things about the ultra flows, they are quiet till you hit the throttle. I like my 3chamber flows OK, they are pretty quiet and have no drone. I will probably swap to the dynomax or Borla, which also make the lower noise/good power type.
i have the same cat back with full lengths and a hpipe. has half as much drone as my mac egual lengths with 2 chamber flowmasters..
Does an x-pipe create more drone than an h-pipe? DOnt get me wrong, the MAC mufflers sound great , but im just curious to see if there is something a little quieter out there.
maybe..headers make a little difference to i'm sure. i put a highflow cat h-pipe on my setup now and wow it came off. it droned big time.
hooker max flows..the shop i take my mustang to cant believe how quiet my car is....they outflow most too and they are loud as the loudest mufflers at wot. kinda raspy though good luck
