      Great sound

      As much as I liked the sound of my Flowmaster mufflers, when I added off road cat-less X-pipes, the cabin noise and drone effect was absolutely awful and it gave one a headache while riding in the car at all. When I switched to these Magnaflow mufflers, the terrible droning noise in the cabin was replaced by the strong rumble that Magnaflow is known for. Well worth the change

      way better than flowmaster sound to me

      Well when I got car had factory x pipe with all cats remove and 40 flowmasters. It sounded good to some people. To me to loud and the drone inside of car was just to much. Lol getting older and wanted a better quality sound and lower tones from exhaust. Put the magnaflow catted x pipe in and then topped it of with these magnaflows from american muscle and couldn't be happier. So much smoother of a sound. Lower and just a very clean sounding exhaust. Not for the guys who want to have the loudest but if you want a good clean exhaust magnaflow is the way to go

      Best in the business

      Bought these to replace my old three chamber loud and obnoxious mufflers and i wish i would have sooner. It was so easy to order get my new mufflers and get them exactly when American Muscle said i would. Fit was perefect took a little longer than i thought to take the old mufflers off but overall not bad. The sound is incredible its much more tame sounding but at high rpm you can deffinately hear the roar of the engine come out. Gotta be the best mufflers out there I absolutely love them i recommend to any mustang owner for sure.

      Great Product

      Completely changed the sound of my car, has a nice deep tone to it. Not too quiet, but also not loud enough to wake up the neighbors. Great product overall.

      Good Sound But Quieter Than Expected

      I bought these mufflers because the other mufflers I had droned a lot on the highway. These mufflers definitely took away the drone that I was experiencing. It still has a good throaty growl when you rev it up, and when cruising around, but it is quite a bit quieter than I thought it would be. The install took 2 hangers, and about 4 pieces of extra tubing to get it fit in there. When I installed mine it required welding because of the catback system I have in place, and it took about 2 hours to do. If you want good sound with less drone on the highway, I would recommend these.
