GrimmSpeed Ceramic Coated Uppipe - 2004+ Subaru STI | 2008-2014 WRX
The GrimmSpeed Uppipe is hands down one of the best uppipes on the market. This particular uppipe has larger diameter piping which allows fewer restrictions, and increased spool time.
Other features include a sleek black ceramic coated finish to help deflect heat, and decrease engine bay temperatures. The pipe itself is fabricated out of 304 SS, and has a pipe-wall thickness of 2.0mm. The inlet size is 1.93 inches, and the outlet size is 1.72 inches. This makes for a smooth transition and best air flow quality out of the turbo. Finally a flex joint is added to ensure a life expectancy out of this uppipe.
Included is the uppipe, 5 studs, and 2 nuts with bolts. Also included are the gaskets necessary for the installation.
