Description

The Stainless Works SM15HCAT Stainless Power Headers are engineered for the 2015-2017 Ford Mustang GT, offering a significant upgrade over stock. Constructed from durable Tig welded 304 stainless steel, these long tube headers feature 1-7/8 inch primary tubes and 3-inch diameter slip-fit collectors with merge spikes. The 3/8 inch thick flanges ensure a secure and robust connection. This system replaces the factory manifolds and catalytic converters, integrating seamlessly with the factory connection point via 3-inch diameter catted lead pipes. The "Stainless Power" line emphasizes maximizing engine output. The "Mill" finish provides a clean, natural look. While they include high-flow catalytic converters, it's important to note that this system is not California legal. The Stainless Works SM15HCAT headers are backed by a 24-month guarantee on material and workmanship, assuring quality and durability.
