CP-e Ford Focus ST 3" Offroad Downpipe

*image is only a representation and may not be accurate

Following the same successful recipe we have used for our other downpipes, our Focus downpipe replaces the choked factory pipe and its restrictive cat, with one high-flow cat and a 3" mandrel bent pipe.  The catalytic converter features a high-flow, all metallic honeycomb design, making it one of the most durable converters on the market.  The result of our efforts is reduced backpressure, decreased turbo spool time, and improved dyno results – more than 5% gains.  For an even greater dose of the same great sound and power, opt out the catalytic converter and get our off-road-use-only downpipe.

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

Matching the stock turbo, our downpipe includes a CNC lathed V-Band flange for easy installation and stock compatibility.  Our downpipe is crafted from premium "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.

The most unique feature of this downpipe that certainly sets it apart from the rest is the exhaust exit end.  cp-e™ has designed two separate ends to allow the user to buy one downpipe for any cat-back exhaust system.  The user is able to slip on one end for the stock 2.50” cat-back exhaust, or switch out to the 3.00” end for an aftermarket cat-back exhaust.  This adjustability allows this to be the last downpipe the user needs to buy, as opposed to buying separate downpipes for each setup.  This adjustability isn’t the only benefit with this design though; by having a setup of this design the user can ensure that their exhaust gases are flowing into their exhaust with the least turbulent and most free flowing design available.  This benefit adds to performance, and also helps prevent unwanted exhaust gas leaks that can come from improperly matching the transition joint into the cat-back exhaust.    Lastly, both ends will be included with the downpipe in order to prevent the need for an additional purchase at a later date.  Both ends include appropriately sized flanges that are 3/8" thick laser cut 304 stainless steel.

To keep the quality high, cp-e™ has used TIG welds to secure each piece of the downpipe.  TIG welds are usually avoided in this industry because they require more time and skill than a MIG weld, despite the fact that TIG welds are better suited for thin metals, are better looking, and create a more durable bond.  We held nothing back with this product.

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.
