These systems are designed to directly replace original mufflers using factory hangers and connections. With easy fit in mind, these units utilize mandrel bent tubing (where applicable) for maximum performance and include specially selected mufflers. Direct-fit mufflers deliver a moderate interior and exterior tone and are suited to the enthusiast who wants their performance to be heard without breaking the bank. Like all Flow master systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.
