This Flowmaster® Force II® system features true dual 2.25-inch mandrel-bent stainless steel tubing flowing into our exclusive Scavenger Series® X-pipe for maximum power and a deep unique tone. The tubing then flows into a specially designed pair of 60 Series™ performance mufflers and delivers a moderate exterior tone, with a mild interior tone. The mufflers are finished off with a large pair of 3.00-inch polished stainless steel tips and the system comes with a template to trim the lower valance for that true dual exhaust look and sound. Like all Flowmaster 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 and is covered by our Lifetime Limited Warranty. Note: Requires a cut-out to be made in the rear bumper valance to accommodate the left side exhaust tip (template included).
