Product Overview

Looking for a smooth transition between the Mishimoto EcoBoost downpipe and the Mishimoto EcoBoost Cat-Back Exhaust?

The Mishimoto Mustang EcoBoost Exhaust Adapter is made a 304 Stainless Steel that will not rust in harsh climates and installs in under 30 minutes. This adapter perfectly complements the V-band flange on the Mishimoto downpipe and the 3” band clamp on the Mishimoto cat-back exhaust. And like all Mishimoto Mustang EcoBoost parts, this Adapter comes with the Mishimoto Lifetime Warranty.
