After running Ultraflows on my fox body for years I decided to try them on my 13 GT. I Bought these to replace my GT500 mufflers and couldn't be happier with the change in sound. It's a deeper sound that's much quiter at idle than the GT500 mufflers. At WOT they get louder but not obnoxious. I was disappointed in the condition they arrived in though. The collector on one of them was dented which I was able to straighten out and one of the tips was dented and scratched. Dynomax should package them better to prevent this type of damage. The mufflers also sit angled once mounted, not flat like OEM. You could probably modify the inlet side of the exhaust and shorten the pipe to correct this but it should fit like OEM in my opinion. Overall I love the sound of the mufflers just a little disappointed in the fitment.
Yes, I would recommend this item to a friend!

Just put these on my 14 GT yesterday. I had Ultraflos on my '83 GT and my '00 GT before this and loved them. They are not loud, just deep and just right volume-wise. You could do a resonator delete to make these louder if desired. It is a 3" core and straight through design so can't be beat for overall flow. Fit was ok, but the Dynomax engraved tip is not centered on the top of my driver's side muffler. There is very little adjustment to the way this sits, so nothing I can do except cut and reweld it in the correct location. It's possible I could twist and bend the hangers to correct also. I also had to pull the clamps down REALLY HARD for them to bite onto the stock extension pipes. One other note is that the tips stock out pretty far, but they look great.
