cp-e 3" Downpipe for Ford Focus ST

cp-e Focus ST downpipe includes a CNC lathed V-Band flange for easy installation and stock compatibility. This downpipe is crafted from premium "bright annealed" 304 stainless steel and is mandrel bent throughout for less turbulent exhaust flow. cp-e has included three O2 bungs to accommodate the two stock O2 sensors, and to give the ability to easily add a wideband sensor.  cp-e offers 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. 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 Focus ST Catless 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.

The downpipe comes complete with all necessary hardware required for a complete and professional installation, is made in the U.S.A, and includes a full lifetime warranty.
