High-quality replacement TMIC Y-Pipe Kit

The Grimmspeed TMIC Y-Pipe has been completely redesigned to make use of a single-piece aluminum casting that's machined after the casting process to ensure perfectly flat flanges and precise fitment every single time. With inspiration from the OEM Y-Pipe, Grimmspeed Engineers set out to balance the airflow through the y-pipe to evenly distribute charge air across the inlet end tank on your top mount intercooler.

The 5-ply silicone couplers are fiber-reinforced to prevent distortion in high boost scenarios but offer mobility and flexibility, isolating your TMIC assembly from the vibrations of your engine. Each 90-degree coupler is slightly oversized on the turbo side so that it can be trimmed to fit with a number of different stock location turbos. This y-pipe is exactly what you need in order to upgrade your WRX intercooler to an STI or Grimmspeed TMIC. If you've got an STI, the Grimmspeed Y-Pipe offers a fresh look and better flow distribution. All kits come with a replacement 90deg turbo outlet coupler, throttle body coupler, and stainless steel BREEZE high-torque clamps.
