Aggressive Race-Oriented Exhaust System
Flowmaster Outlaw Series Exhaust Systems feature race-bred components that ensure minimal flow restriction (slight sound reduction) over open exhaust tubing on vehicles without catalytic converters. With easy fit in mind, these systems are mandrel-bent for maximum performance and mount using stock hanger locations. Outlaw systems are dyno-tuned to improve throttle response, deliver an ultra-aggressive interior/exterior tone, and include all necessary parts and hardware for easy installation.
