Show original supplier description
This Y-pipe features a redesigned one-piece aluminum casting with precisely machined flanges for a perfect fit and reliable, leak-free seal. The 5-ply, high-grade silicone couplers are fiber-reinforced to resist distortion under high boost conditions, ensuring they maintain their shape while also providing flexibility to isolate the TMIC assembly from engine vibrations. The kit comes complete with stainless steel high-torque clamps and black zinc-coated hardware for a durable and clean installation. Designed for balanced airflow distribution across the intercooler's inlet end tank, this Y-pipe kit includes a 90-degree turbo outlet coupler, a throttle body coupler, and all necessary clamps. The turbo outlet coupler is slightly oversized and may require trimming to fit various stock-location turbo setups, ensuring adaptability. This Y-pipe is compatible with the following Subaru models when equipped with a factory or GrimmSpeed Top Mount Intercooler: 2004-2021 Subaru STI, 2002-2007 Subaru WRX, 2004-2008 Subaru Forester XT, and 2004-2006 Subaru Baja XT.
