This Flowmaster mid-pipe system fits 2015-2023 Ford Mustangs with the 2.3L Ecoboost engine and is a great way to increase the sound level and performance of your Pony by removing the factory resonator. These Y-pipe assemblies use Flowmaster's exclusive D-port technology and can be used with either the factory rear mufflers or with one of our Axle-back exhaust systems. Constructed with mandrel-bent 2.50-inch stainless steel tubing flowing into a Scavenger Series Y-collector, then splitting into dual 2.25-inch mandrel-bent stainless steel tubing to connect to the axle back muffler assembly. Includes all parts, necessary hardware and easy to follow instructions for installation. Covered by our Flowmaster Lifetime Limited Warranty. Notes: Fits coupes and convertibles.
