Customized Fit. Let your 5.0L F-150's engine breathe easier by replacing the stock exhaust manifolds with these high-flow long tube headers and catted y-pipe combo. Stainless Works specifically made this exhaust system to bolt up directly your F-150's existing stock cat-back, so there are no additional components to purchase.

High Flow Catalytic Converters. Stainless Work's high flowing catalytic converters are engineered to outperform the restrictive stock cats. The included high flow catalytic converters provide a significant increase in exhaust flow for a measured improvement in horsepower and torque at the rear wheels.

Solid Construction. Made only of 304L stainless steel, you can rely on these headers to put up with a lot of abuse. They resist corrosion, high levels of heat and debris flying up from the road or trail. The layout includes 1-3/4-inch primary pipes, 3-inch slip fit collectors and 3-inch catted leads for excellent flow-through.

Reliable Performance. Installation is straightforward, with a design that fits on your stock engine and exhaust system without any modifications. In fact, you can use the factory connection point to join the Y-pipe. All bends and transitions are smooth, allowing the air to slip through without unnecessary obstacles.

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 Catted 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
Technical Note. This Stainless Works product is not legal for use in California or other states adopting California emission standards; intended for off road use only.

I have a 2013 ford f150 supercrew 6.5' bed; What is it about the stainless works headers that do not allow it to fit this specific wheelbase F150? What are my options to get this to fit?


Can these be used with the stock catback exhaust?


  • Hello! These headers are designed to work with your stock catback exhaust!

Will this create the droning sound when towing at 200-2500 rpm range. I other words how aggressive is the sound


  • These headers will have a different sound depending on the cat-back portion of the exhaust. If the stock cat-back is used the sound will be on the mellow side with some slight increase in aggressiveness.
