Stainless Works GT350CBHPCL Legend Cat-Back Exhaust H-Pipe with NPP Valve

The Stainless Works Legend cat-back exhaust system is engineered specifically for 2015+ Ford Shelby GT350 and GT350R models, delivering enhanced sound and performance while maintaining a comfortable daily-driving experience. This system features Stainless Works' proprietary drone-free muffler design, tuned specifically for the high-revving Voodoo flat-plane crank V8 engine.

Active Exhaust Technology:

The system includes an in-house engineered NPP (noise position profile) valve that integrates directly with the factory electronics, enabling full control over all three exhaust modes. Quiet mode closes the valve for restrained sound levels, Normal mode utilizes the chambered design for the signature Stainless Works growl, and Track mode opens wide for straight-through flow and maximum volume. The valve operates seamlessly with your vehicle's existing exhaust mode controls.

Performance-Oriented Design:

• 3-inch mandrel-bent tubing with H-pipe crossover design for improved exhaust flow over factory system
• Drone-free muffler technology engineered for the GT350's unique flat-plane engine characteristics
• Performance connection design fits directly to factory intermediate pipes
• Utilizes factory exhaust tips and exits through OEM valance location
• Designed to increase volume and improve exhaust tone while maintaining cabin comfort

Construction and Warranty:

The Legend series represents Stainless Works' approach to daily-driver exhaust systems—delivering enhanced sound and performance without sacrificing comfort.
