Perrin Big Tube Uppipe - WRX 2002-2014 / STI 2004-2019 / More
PERRIN has been known since their inception for the quality of their up-pipes. The up-pipe was the first product they ever released and has been a leader in this market ever since. A Perrin up-pipe is one of the best ways to increase the power and throttle response on your turbocharged Subaru.

321 stainless steel tubing is CNC mandrel bent and precision welded to perfection. This eliminates the need for a flex joint, which is a major weakness in other up pipes including the OEM one.
The PERRIN Big Tube Up-Pipe has a 2" diameter which best matches aftermarket headers and the inlets of aftermarket turbos. This image shows the difference between the standard up-pipe (right) and the Big Tube Up-Pipe.(left)
PERRIN Flanges are CNC machined from 304 stainless steel and counterbored on the back side to make smoother transitions from heads to tubing and header to up-pipe.
