Description
Non-Restrictive Design. The Stainless Works 1-3/4 in. Long Tube Headers with Catted Y-Pipe is designed to replace the restrictive factory manifold to improve performance. In addition to the long tube design, the headers have an internal spike design provides a maximized scavenging effect that dramatically improves engine performance and mileage.
Increased Tone and Volume. Another benefit of the long tube header design is that it provides an excellent sound that is louder than stock but still civilized. Aftermarket exhausts can help to further fine-tune this sound.
Includes High-Flow Catalytic Converters. The headers incorporate non-restrictive high-flow converters to provide the smoothest exhaust flow while still keeping emissions in check. Additionally, the high-flow design helps to increase torque-horsepower.
High-Quality Stainless Steel Construction. Stainless Works use Everlast-grade stainless steel in their products. Not only does it provide exceptional strength and heat-resistance, the material protects the headers from rust and corrosion.
No Tune Required. The Long Tube Headers are designed to work and provide performance benefits without a computer tune after installation. However, a computer tune is recommended to allow your truck to fully realize the potential of the new headers.
Not CARB Certified. These Headers are not CARB certified and are not legal for use in California or any other state adopting California emission standards. Intended for off-road use only.
Application. The Stainless Works 1-3/4 in. Long Tube Headers with Catted Y-Pipe will fit 2004 to 2008 Ford F-150 5.4L SuperCab with a 6.5 ft. Bed and SuperCrew models.
