Product Description

An easy pairing that includes both adapters and hardware kit (which are available separately).


The stock turbo adapter on the Ford F-150 / Raptor Ecoboost motors is a known restriction in the exhaust flow. Our new design improves on the OEM piece by starting with a fresh stainless steel casting. The design has an increased cross section with smooth taper that is matched to the oval-shaped turbo side opening. This makes for seamless transition as air flows from the turbo and into the downpipe. Total volume of the flow section is increased from 9.8 to 10.1in3. The minimum internal cross sectional area is increased from 3.4 to 4.2in2, a 23% increase. 

This design was chosen with the aid of CAD Flow Simulation, with the goal being to maximize flow while still maintaining enough material to handle the heat and pressure of the exhaust gasses. Simulation results show that the increased flow area reduces turbo side pressure 55.8% from stock while increasing (and smoothing) velocity to 101.1% of stock. Faster and easier flow means that the motor can apply more power to the wheels instead of forcing air through the exhaust. The increased flow is much more noticeable when more air is traveling through the exhaust, which will increase top end power as well as lower spool time.

Dyno testing showed a +14HP and +1ft-lbs peak gain, with torque peaking 212RPMs earlier than stock! Max gain (biggest difference at RPM and most noticeable as the change in actual driving) is +30HP at 5300RPMs and +23ft-lbs at 5600 RPMs. The curves show improvement with torque coming on slightly earlier, and the biggest increase is at the higher RPMs. There was also an increase in peak boost pressure, going from 20.8 to 21.77psi. The boost has a steeper curve and builds quicker, hitting peak at 3273 RPMs vs 3379 when stock. The ECU is limiting boost based on the timing of the drops, showing potential for more gains with further tuning. 


  • Max Gain +30HP at 5300RPMs and +23ft-lbs at 5600 RPMs
  • Peak Gain HP +14HP and +1ft-lbs
  • Peak Torque RPM is 212 less than stock, earlier power!
  • Minimum internal cross sectional area increase from 3.4in2 to 4.2in2, a 23% increase
  • Smooth bore and taper from bottom to oval shaped turbo opening
  • 55.8% decrease in pressure while maintaining velocity
  • Fitment for 2011-2020 F-150 and 2017-2020 Raptor 3.5L Ecoboost Models (does not fit 2.7L Ecoboost)
  • Includes 2 adapter flanges (no gaskets or hardware)


The OEM studs are a known failure and problem point when working on the exhaust. The stud only has 2 flats on the end and requires a specialized Ford OE tool or stud extractor to remove, which will usually leave the stud and threads damaged. There is also a high probability that the studs will break when attempting to remove them as the quality of steel and machining does not suit this application. 

We chose to manufacture the stud using 303 Stainless Steel, adding corrosion and heat resistance to the part. The 303 is an easy-to-machine stainless guaranteeing quality threads and a long, reusable lifetime. The design also adds two hex key portions, a 6mm on the head for stationary support while removing the nut from the downpipe, and a 15mm on the center portion for stud installation and extraction. Adding these provisions for use with common wrenches or sockets will make it much easier to remove and allow for easier application of proper torque specs.


  • Contains all components needed for install, 4 studs, 4 nuts, 2 gaskets, and anti-seize
  • 303 stainless studs for corrosion and heat resistance
  • Added hex key portions for easy, reusable studs with common hand tools
  • 6mm outer portion for stationary support when just removing downpipe nuts
  • 15mm center portion for install and extraction that won’t strip
  • Single use anti-seize packet added to prevent galvanic corrosion between the various metals
  • New gaskets for perfect seal
