      Bought my set directly from flowtech but love it so much had to write a review here. They were easy to install I got it done within an hour. I didn't have stock mufflers so I dont know how it compares to that but it is much louder than the no name mufflers the previous owner had on it and I get a lot more crackles/pops from the exhaust now. I haven't noticed any bad droning and I daily it on the interstate.

      sounds good

      like the way they sound, deep tone no rasp, which is what we wanted. little louder than expected or wanted but will be keeping them. still have cats so well see how they are after headers and no cats. had to bend the hanger a little to get lined up correctly with the tips and bumper. did not see any hp gains that i can tell but thats to be expected out of any axel back. more sound, lot better than stock.

      Great Product

      If you want your v6 to have an amazing sound get this. I bought this product a few months ago and it sounded great by itself, I then paired it with the flow master x-pipe and it sounds like a GTR. If you want your mustang to sound as fast as it is buy this and an x-pipe.
