  Great price, easy install, and awesome sound!
By on 2/17/2014
I shopped a lot of exhaust options on Youtube, knowing that the microphone doesn't adequately represent the true sound of a system. My initial reaction was to go with something much more expensive, do to the notion that price is an indication of the quality I would find; yet despite my acceptance of the distortion of camera microphones I kept returning to the Flowmaster Outlaw videos. I liked how they sounded even in the videos. I decided to take a chance, since the Outlaw system wasn't as expensive as others, and try them out. I am glad I did, the sound is much more rich than the Youtube videos, and while it does drone a bit; to me that is music to my ears. If you are looking for a sound change, and dislike the sweet note of aggression soothing your ears at 2k RPM, then you may want something else. If you like the raw aggression and having to turn up your radio because the exhaust is drowning it, then the Outlaws are your system! The price was great, the installation was easy and straight forward, and the reward was the grin I wore when I first started my 5.0 and heard it come to life!

Yes, I would recommend this item to a friend!

  Perfect Fit!!!

I bought the Flowmaster Axle back Outlaw Exhaust and couldn't be happier. I have a 2013 GT Coupe and was looking for something to beef up the stock sound and this definitely did it! Listening to the different sounds was difficult as the sound quality from my speakers was not the best. I checked around, did some research but in the end Flowmasters won. There is a slight drone around 2000 RPM which may bother some but I rather like it. Turn up the radio? I say roll down the windows. So why did I choose this product? The price was right, the installation was quick and easy and the sound rocks!!!!

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."
