Stainless Works 1-3/4" Long Tube Headers Off-Road Factory Connect System 2004-2008 F150 5.4L
Awesome New Levels of Performance, Power and Sound for your F150
Long tube headers are some of the most power bolt-on performance parts that you can find for your F150's 5.4L Triton V8, but they're even better when paired with a mid-pipe system that gives your tough truck something everything it needs all in one place. This complete Stainless Works long tube header and mid-pipe package comes standard with a set of Stainless Works 1-3/4" long tube headers that are then paired with a Stainless Works catted mid-pipe that has one of Stainless Works Factory Connect tubing configurations for fitting on your stock and most other standard cat-back exhaust systems. With the proper cat-back, this system works to give your truck a powerful True-Dual exhaust system instead of standard Y-pipe for huge gains in power, sound, and overall performance. The headers and mid-pipe bolt on right in place of your factory exhaust manifolds and Y-pipe and will get your truck huge gains in power after it required custom tuning.
High-Quality 304L Stainless Steel Construction with Extremely Efficient Design
The Stainless Works long tube headers included in this package bolt on right to your 5.4L V8's exhaust ports and make for awesome, high-quality replacements of your F150 notorious factory manifolds. Each header is built a round a set of 1-3/4" primary tubes that are each mandrel-bent to ensure smooth exhaust flow with limited restrictions and back pressure. The primary tubes drop down into a large 2-1/2" collector housing that's fitted with a specialized internal velocity spike to help maximize scavenging and to quickly shuttle gasses down into the mid-pipe assembly. The mid-pipe is made out of 2.5" diameter mandrel-bent tubing and includes a pair of high-flow catalytic converters with a metallic substrate to reduce rasp. The entire system is made out of high-quality 304L stainless steel that is resistant to corrosion and discoloration in practically and climate or application. The mid-pipe has Stainless Works Factory Connect tubing configuration that fits your stock cat-back and other cat-backs designed for the factory mid-pipe.
