It's unclear why Flowmaster named this the "Outlaw"system. Unlike your stock exhaust that's been robbing you of horsepower, the Outlaw system gives you free horsepower without leaving your pocket book empty. 

Bark & bite. Flowmaster's Outlaw systems extract a aggressive muscle car tone from your 3-valve mod motor. In addition to an authoritative tone, the free flow race style mufflers increase horsepower and are a great complement to bolt on power adders.

The bones. The foundation of this durable system is 16 gauge 409 stainless. The mandrel bent tube measures 2.50" diameter and terminates into 4" diameter polished stainless tips. The polished tips feature an embossed "Flowmaster" logo and are a nice contrast to the black coating applied to the remainder of the system.

The breed. This system was designed to be compatible with all varieties  of V-8 powered ponies fitting GT, GT500 and Bullitt models. 

Features & Benefits:

  • Dyno proven performance gains
  • Super aggressive sound
  • T409 stainless construction
  • Made in the USA
  • 4" polished tips

Flowmaster Outlaws
I perviously had the BBK Varitunes, way to quiet for me, so I got these flowmasters after weeks of sound clips and research. Completely changed the sound of my 2006 S197. They bring out the muscle car Growl if that's what your looking for, one of the loudest on the market for the S197 IMO. If your on the edge of buying them, don't wait any longer, GET THEM!!!! I was not disappointed.
