Grimmspeed Up Pipe 2002-2014 WRX/2004-2021 STI

The Grimmspeed up pipe replaces the stock up pipe (which has a cat on the 2002-2005 WRX and 2005-2006 Legacy GT), and features super-thick 1/2″ flanges, heavy 14-gauge 2″ mandrel-bent tubing, gorgeous precision TIG welds, and an exquisite brushed finished.  Of course, it’s all stainless steel.

The up pipe does NOT have an EGT bung, so you’ll have to do the “resistor mod” if you have a 2002-2005 WRX.  (Google it if you don’t know what we’re talking about.)

Fresh studs are pre-pressed into the pipe.  Gaskets sold separately.

Fits all 2002-2014 Subaru WRX, 2004-2021 STI, 2005-2009 Legacy GT/Outback XT, and 2003-2013 Forester XT.
