Ultra Aggressive Sound. Want to give your F-150 a throaty, super aggressive sound that turns heads? If so, Flowmaster's Outlaw Cat-Back Exhaust may be right up your alley. This split side and rear exit exhaust has that deep growl you crave, thanks to features such as a stainless steel mandrel bent tubing and a Super 10 Series reflection muffler.

Maximize Performance. Upgrading to this 3-inch Outlaw Cat-Back provides the opportunity to improve exhaust flow over stock and, in turn, superior power and performance for your V8 5.0L F-150.

Stainless Steel Construction. Flowmaster proudly constructs this Outlaw Series Exhaust in the USA. The 3-inch diameter stainless steel mandrel bent tubing is durable and efficient in design, with a reflection-style muffler and 4-inch double-wall stainless steel tips that look rugged in black and ceramic.

Easily Bolts On. This Flowmaster Cat-Back is made for ease of installation, with a bolt-on design and all necessary hardware included. The round tips with embossed logo exiting at the side and rear of the rig look as aggressive as they sound.

Application. The Flowmaster Outlaw Cat-Back Exhaust with Split Side and Rear Exit Exhaust is fit for 2004-2008 5.4L V8 Ford F-150s (2 and 4 Wheel Drive, all Wheelbases).

    Flowmaster Outlaw

    I've had this exhaust on my truck for about six months now and absolutely love it. Parts appear to be high quality and fit together perfectly so install was quick. The exhaust tone is amazing as well - deep, mild idle and a throaty roar at WOT. There is some drone at certain rpm's but it has never bothered me personally. If you're looking for an aggressive catback exhaust for your F-150, I'd highly suggest the Flowmaster Outlaw.
