Looking to craft your own turbo kit? We won’t stop you. Now we’re offering our downpipe from our Atmosphere turbo kit as a stand alone item. Use this with our Mazdaspeed manifold, the turbo of your choice, and your own custom lines to make a custom turbo kit. 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. Our off-road downpipe includes 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 bracket 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.
Finally, the 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 ReRoute version of this downpipe will route the wastegate into the exhaust. This option is substantially more quiet that dumping to atmosphere and is recommended for daily driven vehicles.
The Downscream version of this downpipe will vent the waste exhaust gas to atmosphere. This option is very loud and not recommended for daily driven vehicles.
