EOS Exhaust - Stainless Steel High Flow Cat Down Pipe - Subaru WRX 2008-2014 / STI 2008-2021

A downpipe is one of the first modifications that should be done on your car, as the OEM downpipe contains two very restrictive catalytic converters, killing the power potential of your car. Within our complete lineup of downpipes, you have the option to add a high-flow, 300 cell catalytic converter, fully machined and contoured flanges with beautiful brushed tubes and black ceramic coating. Whether you're racing time attack or to work and back, we've got the perfect downpipe for you.

For those looking to take the finest downpipe one step further and wring out every last ounce of performance, Ours are fully machined with recesses for each tube as well as a beautiful 3D contour to smoothly transition the irregular shape of your internal wastegate outlet into our divorced tube for tighter boost control. In addition to the machined flanges, limited downpipe tubing material has a brushed finish, for a more uniform, refined appearance.

NOTE: Once you have added our downpipe to your vehicle, you must be tuned. Replacing your factory catalytic converter sometimes causes a ‘cat converter efficiency’ check engine light. You can either use tuning to delete this CEL or you can use a mechanical fix. Extreme Online Store aftermarket downpipes modify OEM emissions control devices and are intended only for off-road racing applications.

By purchasing any aftermarket performance product, the customer takes full responsibility for any use, and/or misuse of the product and agrees that Extreme Online Store holds no responsibility for any consequences, legal, or other, of such use and/or misuse.
