If you’re a Subaru owner looking to enhance your ride, the GrimmSpeed GRM.1099.1.SS Up-Pipe is a must-have upgrade. Designed specifically for the Subaru STI (2004-2021), WRX (2006-2014), Forester XT (2006-2013), Legacy GT (2007-2009), and Outback XT (2007-2009), this up-pipe delivers on every front—performance, fitment, and emissions compliance.
Installing a well-engineered up-pipe is one of the best early modifications you can make to your Subaru. The GrimmSpeed Up-Pipe is crafted to improve exhaust flow, reduce turbo lag, and help your turbo spool faster—typically around 300-400 RPM quicker. This means you’ll feel the difference in your daily drive or when you’re pushing your car on the track.
"Installed the GrimmSpeed Up-Pipe on my 2018 WRX, and I noticed a significant drop in turbo lag. The car feels more responsive, and the install was straightforward with all the necessary gaskets included." - WRX Owner
Take your Subaru’s performance to the next level with the GrimmSpeed GRM.1099.1.SS Up-Pipe. It’s not just an upgrade; it’s a game-changer for your driving experience.
