Great purchase
I had heard some negative things about the mishimoto y pipe splitting from some friends so I figured do it once do it right and be done with it and this kit does just that!

Special Fitment Note: Supported fitments include only those vehicles running OEM STI and GrimmSpeed Top Mount Intercoolers. The elbow coupler is sized to fit multiple turbo setups, some trimming may be required.
Just bought an aftermarket or STI TMIC that requires an STI Y-Pipe to fit? Want to replace your chewed up and leaking couplers? Maybe you're just looking to freshen up your engine bay with a touch of GrimmSpeed style. Well, there's something for everybody with the GrimmSpeed Y-Pipe Kit.

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 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.

Got it for my 07 STi
The Y-pipe is great, mounted up easy on my old TurboXS intercooler, just had to finesse a thicker gasket due to the intercooler design. New hoses are the real star, made getting that beast of a TMI back in place.
