Matching the stock turbo, our Mustang EcoBoost Catted Downpipe includes a laser cut turbo flange designed to fit flawlessly with stock Mustang turbo flange. 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.

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 to mate to the stock turbo completely leak-free.

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 Mustang EcoBoost 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.• More than 5% gains in upper RPMs

Matching the stock turbo, our downpipe includes a CNC lathed turbo V-Band 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-eTM 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. cp-e™ has taken the extra step to supply a laser cut gasket adapter with the 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 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-eTM. 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.
