Ditch the dainty OEM plastic charge pipe for the all new ETS Stainless Steel Charge Pipe for the 2022+ Subaru WRX! The OEM Charge Pipe is reduced all the way down to 1.56" at the turbo flange, some of the competitors increase this to 2.25", but ETS' is made from a true 2.5" diameter pipe from the outlet of the turbocharger to the 2.38" machined inlet flange of the TMIC. This provides a nearly 37% Increase over the stock diameter, while creating a smooth transition to the TMIC flange for an optimal flow rate. By removing the corrugated factory charge pipe in lieu of ETS' smooth mandrel bends and increased diameter replacement, you will see heightened throttle response, more efficient airflow, and increased horsepower gains all without the need to adjust the tune - seriously. Couple this with ETS' Top Mount Intercooler for even more performance gains! NOTE - This part is only compatible with the OEM or Direct OEM Replacement Top Mount Intercoolers
