cp-e™ QKspl™ Ford F-150 Raptor EcoBoost Catted Downpipe


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.



Matching the stock turbos, our F-150 Raptor Catted Downpipes include a laser cut turbo flanges. This design fits flawlessly with stock turbo flanges. Premium American made “bright annealed” 304 stainless steel is mandrel bent throughout for less turbulent exhaust flow. We include three O2 bungs to accommodate the two stock O2 sensors. Additionally, we give the ability to easily add a wideband sensor. We offer an optional high flowing catalytic converter. The optional cat features a metallic monolithic honeycomb catalyst designed for maximum flow. For those opting out of the high flow cat, the off-road downpipe includes a cp-e™ Smart O2 Simulator to help eliminate the unwanted check engine light.

Also helping to accommodate the stock mounting, cp-e™ has designed this downpipe to use the stock downpipe support mount by welding a laser cut stainless steel bracket onto each downpipe. This braket mounts the downpipe securely and provides the extra support needed to make it last a lifetime. cp-e™ has taken the extra step to supply a custom laser cut gasket with the downpipe. Specifically this mates to the stock turbo completely leak-free.

F-150 Raptor Catted Downpipe Construction

On the outlet end of the downpipe, we have created a slip joint that allows the installer to mate it to the stock exhaust or a full 3.00” exhaust. 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. This gives the smoothest transition to either exhaust size, and gives the option of “upgrading down the road”. Now you can have a full 3.00” downpipe without sacrificing on what exhaust you have.

Finally, the Raptor Catted 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.

F-150 Downpipe – The Perfect Raptor DP

Bare in mind, without this adapter the 3.00” downpipe will be larger than the stock exhaust flange. Consequently allowing exhaust gases to escape past the gasket. Thanks to this adapter, the customer is buying a true full 3.00” downpipe. Rather than having the limitation of a downpipe that necks down at the flange. Along with the gasket adapter, the downpipe comes with the necessary hardware needed. Additionally, this downpipe will mount 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 Catted Downpipe Highlights

F-150 EcoBoost Downpipe Full 4 Inch Design

Full 3″ Design

Our downpipes for the EcoBoost F-150 feature 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

Factory Fit & 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.
