15-17 Mustang Long Tube Header Kit w/Cats

The PYPES Performance Exhaust 15-17 Mustang Long Tube Header Kit with Cats delivers a complete bolt-on exhaust solution for 2015–2017 Ford Mustang platforms running the Coyote engine. This stainless steel long tube header system combines primary tube sizing of 1.75 to 1.875 inches with a 3-inch collector design, engineered to optimize scavenging efficiency and flow characteristics across the rev range. The integrated catalytic converters and included mid-pipes eliminate the guesswork of secondary sourcing, while gaskets and hardware arrive pre-packed for a straightforward installation process.

Long tube headers improve exhaust gas evacuation by replacing restrictive OEM manifolds with mandrel-bent stainless steel piping. The primary tube diameter—sized between 1.75 and 1.875 inches—matches the Coyote engine's displacement and typical RPM operating window, maximizing velocity without creating backpressure anomalies. The 3-inch collector consolidates exhaust pulses into a common outlet, supporting downstream components like catback systems and resonators. Stainless steel construction resists corrosion from moisture and combustion byproducts, critical for long-term durability in varied climates. The factory cats maintain emissions compliance while preserving flow advantages over stock configurations.

This kit addresses performance enthusiasts and Mustang owners seeking measurable gains in throttle response and engine breathing without secondary modifications. The all-inclusive package—headers, cats, mid-pipes, fasteners, and gaskets—reduces installation time and eliminates compatibility gaps. Users working on 2015–2018 fifth-generation Mustangs with the naturally aspirated 5.0L Coyote will find this system compatible with both manual and automatic platforms. The natural stainless finish provides durability while maintaining a factory-appearance aesthetic if desired.

PYPES Performance has established credibility in the muscle car exhaust market by prioritizing flow engineering and material quality. Long tube headers remain the foundation of any serious bolt-on exhaust upgrade for naturally aspirated engines, delivering reliable mid-range torque and top-end response gains without forced induction complexity.
