cp-e™ QKspl™ Ford Focus RS ECOf™ by GESI® Catted Downpipe


Following the same successful recipe we have used for our other downpipes, our Focus downpipe replaces the choked factory pipe and its restrictive cat. The result of our efforts is reduced backpressure, decreased turbo spool time, and improved dyno results – more than 5% gains.

Includes high flow ECOf™ by GESI® catalytic converters
Our ECOf™ catalytic converters are EPA compliant and the highest yielding washout available in today’s market. No tuning required.

Matching the stock turbo, our Focus RS Catted Downpipe includes a laser cut stainless steel flange for easy installation and stock compatibility. Adding to this, our downpipe is made from premium American made “bright annealed” 304 stainless steel. Similarly it 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.

Focus RS ECOf™ by GESI® Catted Downpipe Fitment

Also helping to accommodate the stock mounting, cp-e™ has designed this downpipe to use the stock downpipe support mount. We accomplish this with a laser cut stainless steel bracket weld onto each downpipe.

cp-e™ has taken the extra step to design a lathe-cut exhaust flange to perfectly mate the cp-e™ downpipe to the factory exhaust. In addition, this will perfectly fit our own Triton™ exhaust or any other factory-fitment exhaust. Also this lathe-cut exhaust flange perfectly seals against the factory flange and takes advantage of the robust factory exhaust gasket to ensure a leak-free installation.

Focus RS ECOf™ by GESI® Catted Downpipe Warranty

Finally, the downpipe features the all-new finish from cp-e™. This satin finish gives a uniform clean finish throughout. As a result, this also strengthens the stainless steel and the welds for added reliability. As always, this product is Made in the U.S.A. and backed by a lifetime warranty, all your bases are covered.
