Design
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 TMIC 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 replacement 90-degree turbo outlet couplers and throttle body couplers.
