The COBB Tuning 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 STi.
