Solid Performance. Installing these Stainless Works 1-3/4 in. Headers with an Off-Road Y-Pipe is a relatively easy way to squeeze more performance out of your 5.0L F-150, helping you to push the envelope and have more fun. This header and y-pipe combo kit is made in America, so you can feel good about purchasing them.

Durable Build. Thanks to the entire setup being made of 304 stainless steel, you can count on these headers to withstand heavy use. They resist corrosion, so driving in snow, through rugged terrain or anywhere else isn't a problem. Extreme temperatures, long running hours and other demands should not damage the pipes.

OEM Reliability. Thanks to a setup that uses the factory connections, you can expect the same level of reliability as with the stock exhaust manifold. That means no loose fittings, strange modifications or exhaust leaks. The primary tubes measure 1-3/4 inch in diameter, while the lead pipe and collector come in at 3 inches for their diameter.

Limited Lifetime Warranty. Stainless Works is so confident in the quality of their exhaust systems that they are backed by a Lifetime Limited Warranty on materials and workmanship.

Calibration Required. Installation of this Stainless Works Exhaust System will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your F-150's ECU you will be able to realize the full power potential that these Long Tube Headers have to offer.

Application. This Stainless Works Factory Connect 1-3/4 in. Long Tube Header and Off-Road Y-Pipe combo kit is specifically designed to fit the 2011-2014 5.0L F-150s with the following cab and bed sizes. 
  • SuperCab with a 6.5 ft. Bed
  • SuperCrew with a 5.5 ft. Bed
