Perrin Big Tube Uppipe WRX (2002-2014) STI (2004-2018)

Product Description

The Perrin Big Tube Up Pipe is for Subaru builders who are using a larger stock location turbo but are limited by the flow rates of a stock sized up pipe. For the WRX, STI and Legacy GT, the Big Tube uppipe utilizes 2" ID 304 stainless steel tubing that is CNC mandrel bent and precisely welded to perfection without the need for a flex section. Flanges are all CNC machined from 1/2", 304 stainless steel to prevent warping and port matching is done for the smoothest possible exhaust flow. A new set of 5 studs are included. Go with the Big Tube to remove restriction on your aftermarket turbo setup and make some big power!
