The Flowmaster Outlaw Exhaust System is Flowmaster's loudest and most extreme exhaust system, providing a race-inspired, aggressive tone inside and out. It features stainless steel mandrel-bent tubing and aluminized-steel Outlaw-series mufflers, offering dyno-proven performance gains. Installation is typically a bolt-on process, and it comes with a limited lifetime warranty. This system is 50 state legal and includes a Super 10 Series Delta Flow muffler.
