About this product

Part #: 815435S

Flowmaster's stainless steel Outlaw mufflers are the ideal solution for race classes requiring mufflers but having no set sound specifications. Available in two lengths, the Outlaw and Outlaw shorty mufflers provide minimal sound reduction with no performance penalty. These small, light mufflers can be installed directly on your header collectors, or mounted in a full exhaust system depending on your class rules or personal preferences.
