High-quality replacement TMIC Y-Pipe Kit. 

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.

Quick Specs

  • 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

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.

fits well

Installation went well, just had to remove once to get intercooler to line up correctly. Only wish it came with a new set of gaskets between y pipe and intercooler. My 2011 STI is running great again. Quality parts and fit well.
