Introducing Flowmaster's new FlowFX Cat-back exhaust system for the 2015-17 Ford Mustang GT with the 5.0L engine. This system is perfect for the person looking for a deep powerful exterior sound while maintaining a moderate interior sound level with all of the performance benefits that you would expect from Flowmaster. New features include dual 3.00-inch mandrel-bent stainless steel tubing flowing into a Scavenger X-pipe for maximum performance and a deep unique muscle tone. The Scavenger X-pipe then flows into a pair of compact round FlowFX "straight-through" performance mufflers with large 3.00-inch cores. The 3.00-inch tailpipes utilize the factory hanger locations and are finished off with large 4.50-inch black ceramic coated stainless tips to complement the factory cutouts. Designed for an easy installation this system includes all necessary parts, hardware, and detailed instructions.Exhaust Type: Cat-BackExit Position: Dual Out RearInlet Inside Diameter: 3.000 in.Material: 409S Stainless SteelTail Pipe Diameter: 4.500 in.Tip Diameter: 4.500 in.Tubing Diameter: 3.000 in.WARNING CA Proposition 65: YesWARNING CA Proposition 65 Message: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
