Grimmspeed Up-pipe - Subaru STI VA
Fits 2006-2014 WRX and 2004+ STI
GrimmSpeed is no stranger when it comes to creating artistic metal pieces that add horsepower. Their up-pipe is no exception. The Grimmspeed Uppipe will eliminate the factory restrictive up-pipe, and with a larger diameter should increase spool and add as much as +10WHP. For the cost and horsepower ratio, you cannot go wrong.
The GrimmSpeed Uppipe is fabricated out of 304 stainless steel and has a pipe thickness of 2.0MM. The inlet size is 1.93”, and the outlet size is 1.72”. The pipe that tapers down to 1.72” acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air quality. The flex joint is not located in the bend, which adds to the life expectancy of the flex section. The outlet size is a perfect match to the most common stock location turbos allowing for a smooth transition into the turbo.
Included will be all the hardware and gaskets to make for a ready installation.
