Process West Silicone Y-Pipe - Subaru WRX / STI (GD) / STI (GRB/GVB)
The Process West Silicone Y-Pipe joins the turbo compressor outlet to the top mount intercooler on the GD Subaru WRX and STI and the 2008-2014 STI. Most aftermarket Y-pipes have one smooth branch and a poor second spout, so the core gets uneven flow. The Process West design splits the charge air evenly across the intercooler.
Note: For top mount intercooler setups. Installation by a professional is recommended.
Features
- Joins the turbo outlet to the top mount intercooler
- Even charge air split across both intercooler inlets
