Flowmaster - Outlaw Series(TM) 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 in. 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. The 4.00 in. polished stainless tips provide a finished look to the American made T409 stainless exhaust system, and Flowmaster's lifetime limited warranty protects the system.
