Bought these not knowing what to expect... and boy am I happy I bought these!!!!! Well worth the money! Took me about two hours to install. Was a pretty simple install. The sound is just amazing! I'm pretty sure my neighbors hate me though!

5 Stars   Awesome muffler

I bought this a few weeks ago for a 2009 GT, I was torn between the American Thunder series and this one, after seeing reviews of the American Thunder being slightly "tin-canish" I settled on the Outlaw and I absolutley fell in love. The install took about an hour, it was so easy my grandmother could have completed it. I thought at first it may end up being too loud, but when I turned the key, a low rumble exited from my exhaust pipe, and when you stomp down on the gas, all hell breaks loose from the rear. This is the best sounding kit I've heard on a mustang, I recommend this kit to anyone that likes a low rumble at idle and a balls to the wall (but not obnoxious) bassy roar when on the gas

Yes, I would recommend this item to a friend!

I bought a set of flow master exhausts for my 2010 mustang. I love them. They sound so awesome on my car. I had tried to purchase these through another company and am still having trouble with them. The only bad thing was them being drop shipped. There was no way to track themthem and know where they were.

5 Stars   Fantastic sound!

Image uploaded by Tristan F. I got these outlaws with a pypes o/r xpipe and my car is one of the loudest cars around. I've been told that my set up is louder than borla attaks. If quiet is what you want don't buy these, they scream! At low range and low gear it sounds real tinny like most 3valve GTs. But low end 4th gear it purrs and growls, it just sounds fantastic!

Yes, I would recommend this item to a friend!

Through use of these dyno's, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground."
