Improve the sound and performance of your 2007–14 Shelby GT500 with premium long tube headers from Stainless Works. American-Made and designed specifically for the 5.4L or 5.8L Trinity engine, these headers feature 1-7/8" primary tubes that are CNC mandrel bent to increase airflow and engineered to create maximum power.
Each system includes 3" slip-fit collectors with merge spikes, high-flow catalytic converters, and lead pipes that merge into your choice of H-pipe or X-pipe crossover for easy connection to your Stainless Works catback or factory exhaust system.
Built from corrosion-resistant 304 stainless steel with 3/8" thick flanges and oval exhaust ports that are an exact match to the factory cylinder head. Fully TIG welded for strength and durability at our state-of-the-art facility in Streetsboro, Ohio — engineered for long-term performance.
