This Cobb Tuning uppipe is crafted from 304L stainless steel with 14-gauge, 2-inch CNC mandrel-bent tubing and cast stainless steel flanges to prevent warping. It eliminates the flex joint for a leak-free design, using heat-treated 4140 steel turbocharger studs rated to class 10.9 with clear zinc plating.

Designed for a direct fit with the OEM 2-bolt exhaust manifold flange, installation requires a 5mm hex for the turbo studs. Compatible with select Subaru models from 2004-2021, including Forester XT, Impreza WRX/WRX STI, Legacy GT, Outback XT, and all 2015-2021 WRX STI trims.
