Cobb SS 3" Catted Downpipe 2008-09 Subaru WRX/STi

The COBB Tuning turbo downpipe for the 2008 Subaru WRX/STi is one of the premier modifications most owners look to upgrade on their vehicle. By opening the diameter of exhaust flow coming out of the turbo, the COBB 2008-09 WRX/STi downpipe unleashes more power potential over the stock restrictive unit.

The COBB Tuning 2008-09 Subaru WRX/STi downpipe begins with the CAD designed bellmouth that directs the air coming out of the turbo. The design permits the air to flow with very little turbulence to the single high flow catalytic converter. This metal substrate cat is highly efficiant, allowing the exhaust to flow much easier than the factory unit ever would. The COBB downpipe, combined with our AccessPORT engine management, is one of the most easy installations for any enthusiast looking to unlock the true potential of their 2008 Subaru WRX/STi.

NOTE: This downpipe features one (1) high flow metal substrate cat
