Raise the volume of your 2015 Mustang EcoBoost exhaust to new levels with the Mishimoto Cat-Back Exhaust for the 2015, 2016, and 2017 Ford Mustang! Mishimoto utilizes a pair of oval mufflers and piping larger than stock makes the volume of your exhaust grow, while giving it a better tone that doesn't have any increased drone. The constructed completely out of mandrel-bent, 304 stainless steel, this exhaust system offers optimal flow to release some power hidden in the Mustang's 4-cylinder turbo engine. The engineering team at Mishimoto tested a bunch of different tip designs before deciding on these classic oval mufflers that produce a beautiful tone without any additional drone. The dual 4.5" double wall polished tips are eye-catching and definitely makes the view better for your rival as you pull away from them on the road or track. The Mishimoto Ecoboost Mustang exhaust is compatible with both manual and automatic transmissions and just like all Mishimoto Mustang EcoBoost parts, comes with the Mishimoto Lifetime Warranty.
