Free up your Focus ST's exhaust flow with the COBB 3" GESi Catted Downpipe!
This direct replacement for the factory downpipe features a 300 cell high flow catalytic converter and 304 stainless steel tubing. The CNC machined v-band flange and 4" flex section ensure perfect OEM-like fitment at the turbocharger. We've added adjustability to the lower downpipe mount by slotting the attachment points. This allows installers to custom-fit each downpipe to a specific car where tolerances may be slightly off. Doing this reduces strain on the rubber isolaters, improving long-term reliability. An all new cast stainless 2-bolt 3" flange aids in both more precise assembly and also reduces stress during installation of the part. Many downpipes utilize a laser cut plate flange at the termination point to the cat-back exhaust. These plates are susceptible to minor warping while they are being welded to the tubing. A cast flange is much more rigid and reduces the possibility of flex while exposed to extreme heat during assembly. This rigidity also comes into play during installation of the downpipe. In the past, we have received reports of warped flanges during installation due to over tightening of the hardware. Over time, this deflection can lead to exhaust leaks. The new cast version will not bend during installation and will allow for a much more reliable seal. To cap it off, a multi-layer steel gasket is used between the downpipe and cat-back exhaust to make for a leak-free junction.
All of these features combine to provide a free flowing exhaust outlet for high energy exhaust gases to reduce turbo back pressure and increase turbo efficiency.
This downpipe is the perfect step towards Stage 3 power! Stage 3 off-the-shelf maps are available for the Focus ST Accessport for a perfectly tuned out-of-the-box experience.
