If you’re looking to upgrade your 2004-2005 Subaru STI, this piping kit is a solid choice. We’re talking about 2.5" OD tubing made from 304 stainless steel, which means it’s built to last. No flimsy stuff here. The pipes are mandrel bent in one piece, so you won’t find any welds or joints that mess with the airflow—just smooth, uninterrupted flow. Trust me, that makes a difference when you’re pushing your car to its limits.
We’ve also added beads at the ends of the pipes. Why? So your couplers stay put, even when you’re really putting the pedal to the metal. And for that extra touch, we finish everything in a wrinkle black powder coat. It looks good and adds a layer of protection.
In short, if you’re keen on getting the most out of your STI, this intercooler piping kit is a no-brainer. It’s designed specifically for the 2004-2005 models, and it pairs perfectly with the 1.75" Stock Turbo Front Mount Intercooler and TurboSmart BOV. Get ready to feel the difference!
