NGK Cat Back Exhaust 2015-2016 Ford Mustang 2.3L EcoBoost

The NGK Cat Back Exhaust 2015-2016 Ford Mustang 2.3L EcoBoost is a complete cat-back system that increases exhaust volume and refines tone while providing improved exhaust flow for potential power recovery and consistent throttle response.

Engineered by Mishimoto, this exhaust uses motorsports-grade materials and construction practices to deliver durable, race-inspired performance suitable for daily driving and spirited use.

• Twin oval mufflers — provide a broader sound character and smoother exhaust pulses, reducing tonal harshness while maintaining an aggressive note.
• Larger diameter piping — lowers backpressure to support higher flow rates, which can help the turbocharger breathe more freely and improve transient response on turbo upgrades.
• Full 304 stainless steel construction — resists corrosion and thermal degradation for long-term reliability in diverse operating conditions.
• Mandrel-bent tubing — preserves internal diameter through bends to maintain steady, high-flow exhaust paths and minimize turbulence losses.

Function-driven design emphasizes measured gains in exhaust efficiency and sound control rather than unchecked volume. The system's combination of high-flow routing and muffler tuning aims to increase usable exhaust flow while avoiding excessive cabin drone during cruising.

Application and compatibility

Designed specifically for 2015–2016 Ford Mustang with the 2.3L EcoBoost engine. Fitment preserves factory mounting points and interface locations for a direct-replacement cat-back installation.

Why choose this system

• Performance exhaust tuning — tailored to the EcoBoost's exhaust characteristics to support turbocharger efficiency and throttle response.
• Durability — 304 stainless steel and Mishimoto engineering practices reduce the need for early replacement or repair.
• Balanced sound — twin oval mufflers and optimized piping provide a performance-oriented note without introducing intrusive drone.
• Simple upgrade path — designed to integrate with common turbo upgrade and supporting modifications without altering factory exhaust routing.
