Process West Silicon Y-Pipe (suits Subaru 02-07 WRX/STI & 08-14 STI)

The Y-Pipe is the connection between the turbo compressor outlet and the intercooler. This pipe due to the design of most Subaru top mount intercoolers takes the shape of the letter 'Y'. Almost all of the aftermarket Y-pipes we see do not distribute the charge airflow along with the intercooler evenly. Their Y-pipe usually consists of one nicely flowing section with an afterthought spout as the second duct.

Once installed it is easy to see that the Process West Silicone Y-Pipe will give perfect charge air distribution. Combining all 3 features of our top-mounted intercooler gives the perfectly designed top-mounted intercooler for Subaru.
