This Mishimoto cat-back exhaust for the Fiesta ST uses 2.5 inch mandrel-bent 304 stainless steel piping to free up the 1.6L EcoBoost while keeping exhaust velocity in check. The resonated mid-pipe softens highway drone for a subdued yet aggressive tone, and the system is TIG-welded and capped with dual 3 inch offset tips in a burnt titanium finish. It installs in under an hour and is backed by the Mishimoto Lifetime Warranty.
