Review & Install Video

Look Great and Sound Great. Your 2005-2010 GT or 2007-2009 GT500 looks great rolling down the street. But if you're not getting that legendary Mustang rumble to go along with those great looks, here's the answer. The Flowmaster Outlaw Cat-Back Exhaust System provides that incredible, low decibel rumble that makes Mustang owners and admirers so loyal. To top it off, the 4” diameter polished stainless steel tips makes your Pony look as powerful as it feels when you're out enjoying the ride or just taking a quick peek while she's waiting in the garage.

Specifications. The Outlaw Cat-Back Exhaust features 2.5” diameter, mandrel bent tubing constructed from race proven, 409 stainless steel. This Cat-Back is finished off with two black outlaw style mufflers and two 4” polished stainless steel tips embossed with the Flowmaster Logo. All Flowmaster exhaust systems are tuned to make sure the sound is great both outside and inside your ride.

Installation. The Cat-Back Exhaust System comes with all clamps and hangers for a complete upgrade from your factory cat-back. This Flowmaster system uses factory mount locations, making installation very straight forward. The kit is covered by Flowmaster's Lifetime Warranty to make this upgrade an easy decision.

Application. This Flowmaster Outlaw Cat-Back Exhaust is specifically designed to fit 2005-2010 GT, Bullitt and GT500 Mustangs equipped with the 4.6L and 5.4L engines.

what will i need to do to apply this exhaust to my 07 v6?

mattewillie

  • You will need to purchase either an H-pipe or an X-pipe that has the same 2.5" piping size as this cat-back exhaust as well as purchasing an exhaust hanger kit to keep these from dangling and/or dragging.

    Awesome Sound

    Just what I was looking for....Flowmaster did an incredible job with these !!! They spent alot of time on perfecting these. They even do these purge/pop sounds on my manual shift Stang when im coming to a stop or downshifting.....its hard to describe but was an unexpected added bonus. These sound awesome when cruising and they sound like a monster when you open it up. I truly am stunned at how good these are. Great quality, sound, and fit !!! Well worth the money. I am very pleased.....thank you Flowmaster !!!

    Great Sound!

    Just installed and sounds great. I thought it would be a little louder, but either way, they still produce a great tone. I would have given it a 5 star, just wish they were a bit louder.
