Mishimoto Cat Back Exhaust 2.5in Stainless 14-16 Fiesta ST

Cat-back exhaust: the Mishimoto Cat Back Exhaust 2.5in Stainless 14-16 Fiesta ST delivers a subdued yet aggressive exhaust tone while retaining the packaging and routing intended for the factory system.

Designed for the 2014–2016 Ford Fiesta ST with the 1.6L EcoBoost, this Mishimoto system uses a 2.5" overall diameter to alter exhaust character without changing vehicle fitment or centerline placement.

• 2.5" overall diameter — provides the described subdued yet aggressive exhaust tone while matching the system’s internal flow profile for the Fiesta ST application.
• Stainless construction — specified in the product title to denote the material used for the exhaust assembly.
• Designed for 1.6L EcoBoost Fiesta ST (2014–2016) — engineered to integrate with the stock exhaust routing and vehicle architecture for direct-fit installation.
• Optional resonated mid-pipe — available as an option to alter the system’s tonal characteristics.
• Mishimoto engineering — leverages the Mishimoto brand’s experience in performance cooling and drivetrain accessories to produce a purpose-built exhaust for the Fiesta ST.

Key functionality and performance considerations:

• Tonal control: The 2.5" diameter and optional resonated mid-pipe give drivers a clear way to tailor the exhaust tone from subdued to more aggressive while maintaining overall system fitment.
• Application-specific design: Built for the 14–16 Fiesta ST with the 1.6L EcoBoost, ensuring parts align with factory mounting points and exhaust routing.
• Brand consistency: The Mishimoto name indicates a focused approach to aftermarket vehicle systems designed for high-performance street and track use.

This exhaust is suitable for Fiesta ST owners seeking a measured increase in exhaust presence and tone customization without modifying core vehicle fitment or routing. It complements turbocharged platforms by offering a clearer exhaust note while remaining compatible with the factory installation layout.
