The COBB Tuning Uppipe is constructed of rugged, 14-gauge, 2-inch diameter polished stainless steel tubing to endure the intense exhaust gas temperatures these turbocharged engines put out. The uppipe inlet diameter matches the inner diameter of the gasket to maximize flow to the turbo. The extra-thick flanges are cut from 1/2" 304 stainless steel to prevent warping and eliminate high pressure exhaust leaks. These kits are made for the Subaru enthusiast looking to unlock power hidden within the vehicles stock exhaust manifold.
