Get the maximum of what you need—quiet power—and the minimum of what you don't—added weight—with Flowmaster Pro Series Outlaw race mufflers. Responding to the increasing number of tracks that regulate sound emissions, Pro Series Outlaws offer the utmost decibel reduction with the least amount of weight and no shortage of power! They're surprisingly quiet, netting a reduction of approximately 8-10 decibels over open headers, and can be run with a turndown for further noise reduction. You can even use them as an addition to your existing exhaust system for quieter sound. Plus, you can run them with methanol or gas engines. Race like a bandit on the run—but legally—with Pro Series Outlaw race mufflers from Flowmaster.
