GrimmSpeed top mount intercooler (TMIC) y-pipe kit is compatible with the STi top mount and the GrimmSpeed top mount. For the 2002-2007 WRX models, you must have an STi TMIC or Grimmspeed TMIC for this y-pipe and coupler to fit. Available with black or red couplers.
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!
- One-Piece Aluminum Casting - Precise fit and smooth flow without distortion
- Thick Flanges - Prevent heat and vibration from cracking casting
- Machined Flanges - Ensures a perfect fit, leak-free seal, every time
- 5-Ply High-Grade Silicone Couplers - Smooth interior to maximize airflow and minimize restriction
- Heat Resistant Reinforcement - Couplers keep their shape, even at high boost levels
- Stainless Steel High-Torque Clamps - Rust-proof construction with smooth operation
- Black Zinc Coated Hardware - Ditch those nasty OEM fasteners
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° 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° turbo outlet couplers and throttle body couplers.
