I just got my duals installed on Friday and yes I am please, they look great and sound good. I do have to go back to the installer, because I noticed some rattling from the pipes. Question though, I believe mines comes with GTB, as they do sound nice, they are pretty quite. I've seen some clips of other Mustangs on You Tube that has FRPP duals and they sound louder, little more throttier, is that becaause they have GTA? do the GTA sound nicer than the GTB? I know on this forum everyone raves on the FRPP (which is why I went with them, because of all the good feedback I read). Now the duals themselve look great and the kit that comes for the V6 adds a little flare to the rear bumper. I guess I was expecting a louder deeper sound than what I have. Any input or advice is appreciated as always.

From the posts I've read the GTB's are more mellow sounding. Keep in mind though you aren't turning it into an 8 cylinder by adding two exhaust pipes so there is a fine line between aggressive and rice.
In my case the GTA's broke in around 9K miles and got a tick or two more agressive sounding. So, I would expect once yours break in they will sound more to your liking.

The GTB's get a little louder after about 100-200 miles (mine did). I wanted the GTA's but not for 400$. The clips on youtube all depend on the camera and microphone. I heard one GTB clip that sounded really good, and another than sounded terrible.
