    Product Details


    Pump up the volume of your 2015 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 EcoBoost exhaust with the Mishimoto EcoBoost Downpipe. The Mishimoto Ecoboost Mustang exhaust fits both manual and automatic transmission vehicles, and just like all Mishimoto Mustang EcoBoost parts, comes with the Mishimoto Lifetime Warranty.
