CP-e QKspl Downpipe Subaru WRX '15- . Stock Flange 3.00" V-Band Back . 304 Stain

SBDP00002T

Matching the stock turbo, our Subaru WRX Catted J Pipe / Downpipe includes a laser cut turbo flange. This design fits flawlessly with stock WRX turbo flange. Premium American made “bright annealed” 304 stainless steel is mandrel bent throughout for less turbulent exhaust flow. We include three O2 bungs to accommodate the two stock O2 sensors. Additionally, we give the ability to easily add a wideband sensor. We offer an optional high flowing catalytic converter. The optional cat features a metallic monolithic honeycomb catalyst designed for maximum flow. For those opting out of the high flow cat, the off-road downpipe includes a cp-e™ Smart O2 Simulator to help eliminate the unwanted check engine light.

The J Pipe sees some extremely high temperatures coming off of the turbo, so we’ve opted to build with 16 gauge stainless steel. This heavyweight material is perfect for longevity in high temperatures and is 0.016″ thicker than the 18 gauge used on most J pipes.

Our Subaru WRX J Pipe was created using 3-D laser scanned CAD data. This allows the design to reuse the stock inlet and outlet locations for best possible fit.

Subaru WRX Catted Downpipe Construction

On the outlet end of the downpipe, we have created a slip joint that allows the installer to mate it to the stock exhaust or a full 3.00” exhaust. 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. This gives the smoothest transition to either exhaust size, and gives the option of “upgrading down the road”. Now you can have a full 3.00” downpipe without sacrificing on what exhaust you have.

Finally, the Subaru WRX Catted 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 Perfect WRX J Pipe / Downpipe

Bare in mind, without this adapter the 3.00” downpipe will be larger than the stock exhaust flange. Consequently allowing exhaust gases to escape past the gasket. Thanks to this adapter, the customer is buying a true full 3.00” downpipe. Rather than having the limitation of a downpipe that necks down at the flange. Along with the gasket adapter, the downpipe comes with the necessary hardware needed. Additionally, this downpipe will mount to a stock exhaust system as well as an aftermarket exhaust system.

While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state.
