Pump up the volume of your 2015+ Ford Mustang EcoBoost exhaust! The utilization of twin oval mufflers and larger diameter piping makes for a nice increase in volume and tone without any increased drone. The full 304 stainless steel, mandrel-bent construction provides optimal flow to free up some power in that 4 cylinder turbo engine. The engineering team went through a few different tip designs before settling on these classic oval mufflers that provide a sweet tone with no added drone. The dual 4.5"double wall polished tips will be sure to give your opponent a nice view at the local drag strip. If you want the best in exhaust performance, pair this 2015+ Ford Mustang EcoBoost exhaust with the Mishimoto 2015+ Ford Mustang EcoBoost Downpipe. The Mishimoto 2015+ Ford Mustang EcoBoost Mustang exhaust fits both manual and automatic transmission vehicles, and just like all Mishimoto 2015+ Ford Mustang EcoBoost parts, comes with the Mishimoto Lifetime Warranty.
