These quieter sounding systems are designed to replace original rear mounted mufflers located behind the rear axle using factory style connections. With easy fit in mind, these systems are mandrel bent for maximum performance, include specially selected mufflers and all necessary parts and hardware for easy installation. Force II systems deliver a moderate exterior tone and moderate to mild interior tone, and are suited to customers looking for efficiency improvements without a lot of noise. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage.
