GrimmSpeed EWG Up Pipe w/ Dump Tube for 3 Bolt Inlet 44/45mm V-Band - 02-14 WRX/04+ STi



Vehicle Fitment:
2002-2014 Subaru WRX
2004-2018 Subaru STi

This Grimmspeed up pipe is made with a 3-bolt lower flange (which is a perfect match for the Tomei header) and features a 44/45mm external wastegate flange allowing you to convert your internally gated setup to an external, v-band wastegate with dump tube.

The entire external wastegate (EWG) up-pipe is made of 304 stainless steel (flanges, flex, tubing) and has a pipe-wall thickness of 14 gauge. This is the most "heavy-duty" pipe you will find! Many other pipes use cheap thin steel and are marketed as "super light weight."

The inlet size is 1.92" and the pipe tapers down to 1.72” which acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air-flow quality.

The one-of-a-kind triple layer flex joint is not located in the bend, which adds to the life expectancy of the flex section. This outlet size is a perfect match to most common stock location turbos allowing for a smooth transition into the turbo.
