Cat Back Exhaust System 21- Ford F150 3.5/5.0L

The Cat Back Exhaust System 21- Ford F150 3.5/5.0L by FLOWMASTER is an ideal upgrade for modern F-150 owners looking to enhance their vehicle's performance and sound. This exhaust system is designed for those who want improved throttle response and fuel efficiency without the need for custom fabrication or tuning. It is perfect for daily drivers and weekend haulers alike.

This cat-back exhaust system replaces the factory piping downstream of the catalytic converter, ensuring emissions compliance while unlocking horsepower that is often restricted by OEM silencers. FLOWMASTER utilizes mandrel-bent tubing and high-flow muffler technology to minimize backpressure and maintain structural integrity, even under heavy towing conditions. The stainless-steel construction provides excellent corrosion resistance, making it suitable for harsh climates.

This exhaust system is compatible with 2021 and newer Ford F-150 models equipped with either the 3.5L twin-turbocharged EcoBoost or the 5.0L naturally aspirated V8 engine. The dual outlet design not only enhances the visual stance of the truck but also promotes balanced exhaust scavenging across both cylinder banks. With precision-engineered exit velocity, it improves cold-start warmup and reduces turbo lag, resulting in snappier acceleration and smoother power delivery.
