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. Replacing these with our single high-flow unit will dramatically improve performance potential while maintaining the use of a catalytic converter. Within our complete lineup of downpipes, you have the option to add a high-flow, 300 cell catalytic converter, fully machined and contoured flanges 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, we offer our ‘Limited’ line of downpipes. Limited downpipes use flanges made of the very same 1/2″ 304L Stainless material, but 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. Limited downpipes also come in a ceramic thermal coated version which are some of the best downpipes you can buy for your Subaru.

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. GrimmSpeed aftermarket downpipes modify OEM emissions control devices and are intended only for off-road racing applications.
