Product Description

Make some aggressive sound with your 13-14 Mustang 5.0 with the Flowmaster Outlaw Cat Back Exhaust System. The Outlaw Cat-back exhaust systems feature race-bred Outlaw mufflers for a very aggressive track-oriented sound inside the car and out. Featuring 3.00 inch mandrel-bent piping, this Outlaw system bolts directly behind the OE cats with our Scavenger X pipe assembly and delivers noticeable increases in horsepower and torque, while maintaining 50-state emissions legality. 4.00 inch polished stainless tips provide a finished look to the American made T409 stainless exhaust system, and Flowmaster's lifetime limited warranty protects the system. Please note: This exhaust may exceed sound ordinances in some areas. Please check local laws before ordering.

  Great sound poor fitment
By on 3/14/2014
I love the sound this exhaust gives my car. After I installed it, everything appeared to fit perfect. However after my first long drive I went around my car to check fitment and found that the tip on the left side had somehow found its way onto my bumper and had proceeded to melt into my bumper!!!! Talk about pissed off. I had just bought the car!!! It cleared plenty upon original install. Had to bend exhaust hanger to fix this. You figure for 800$ you wouldn't have to modify it.
From LatemodelRestoration.com: Several short drives to allow expansion and contraction followed by checking all clamps will prevent this type of situation.
Yes, I would recommend this item to a friend!

  Customer Service ROCKS!!!!
By on 7/2/2014
I recently ordered the Flow Master Outlaw Cat backs for my 2014 GT. I was having trouble getting shipping info on the drop order and contacted LMR. Lee Cox immediately responded and contacted Flow Master and worked on getting me the info I requested. Lee, you are what customer service is all about. I will definitely use LMR for my future mods just based on the help Lee gave me.
