The real meat and potatoes of any turbocharger’s exhaust system is the downpipe. The downpipe is responsible for transporting waste exhaust away from the turbine wheel as efficiently as possible. And more often than not factory downpipes are designed with emissions as the primary consideration, not performance.

Also available with a catalytic converter.

Raptor EcoBoost Off-Road Downpipe

Although more power and great sound are high priority items when buying a 3″ Raptor EcoBoost Downpipe, the fine details are what ensure that the product will satisfy the end-user for a lifetime:

Matching the stock turbo, our Raptor EcoBoost Downpipe includes a CNC milled turbo flange for easy installation and stock compatibility. Our downpipe is crafted from premium American made “bright annealed” 304 stainless steel and is mandrel bent throughout for less turbulent exhaust flow. We have included three O2 bungs to accommodate the two stock O2 sensors, and to give the ability to easily add a wideband sensor. We offer an optional high flowing catalytic converter that features a metallic monolithic honeycomb catalyst designed for maximum flow and surface area. For those that opt-out of the high flowing cat, the off-road downpipe will include a cp-e™ Smart O2 Simulator to help eliminate the unwanted check engine light.

Raptor EcoBoost Off-Road Downpipe Features

  • 5% gains throughout RPM band
  • Removes the factory donut-style turbo exhaust reducers
  • Extra O2 bung for adding a wideband sensor
  • Factory location exhaust hangers
  • CNC cut flange made exactly to the factory profile
  • Full 3″ mandrel bent 304 stainless steel
  • Included Smart O2 Simulator with Off-Road Downpipe
  • Strengthening & Uniform satin finish
  • Made in the U.S.A.
  • Lifetime Warranty

Also helping to accommodate the stock mounting, cp-e™ has designed this downpipe to fit the stock catback without a gasket by designing a CNC cut flange made exactly to the factory profile. In addition, our downpipes remove the factory “donut-style” turbo exhaust reducers and will mount directly to the turbine housing. This eliminates that bottle-neck and provides a two-in-one solution so you won’t need to buy a separate adapter for optimum flow.

cp-e™ has taken the extra step to supply a laser cut gasket adapter with the F-150 Raptor Downpipe. This adapter will allow the installer to install the downpipe to a stock exhaust without the worry of exhaust leaks. Without this adapter the 3.00” downpipe will be larger than the stock exhaust flange, allowing exhaust gases to escape past the gasket. This adapter allows the customer to buy a true full 3.00” downpipe instead of being limited to a downpipe that needs to neck down at the flange. Along with the gasket adapter, the F-150 EcoBoost Downpipe comes with the necessary hardware needed to mount it to a stock exhaust system as well as an aftermarket exhaust system.

Finally, the downpipe features the all-new finish from cp-e™. This satin finish not only gives a uniform clean finish throughout, but also strengthens the stainless steel and the welds for added reliability. Made in the U.S.A. and backed by a lifetime warranty, all your bases are covered.


While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state.

Raptor EcoBoost Off-Road Downpipe Highlights

F-150 EcoBoost Downpipe Full 4 Inch Design

Full 3″ Design

Our downpipes for the EcoBoost F-150 were designed with maximum flow and the quickest spool times in mind. To accomplish this, we went with a full 3″ design directly off of the turbos.This promotes quick spool while maintaining the needed back pressure.

F-150 EcoBoost DownpipeHigh flow catalytic converter

Optional High Flow Cat

The cp-e™ F-150 EcoBoost Downpipe is available with or without a high flow catalytic converter. Maximum gains can be found without a cat, but the catted version is incredibly high flowing and sees extremely low parasitic loss from the catalytic converter.

“Factory Fit and Finish

This QKspl™ downpipe system is manufactured for a perfect fit and finish. This downpipe will work perfectly with your stock cat back for a stealth install or along with our forthcoming Austenite™ exhaust system for the most pure sound. Thanks to a CNC cut flange, the downpipes will fit the factory cat-back perfectly.
