Select the year of your Subaru WRX STI:
If you're looking to switch up your Subaru STI's blow off valve game, this replacement blow off valve pipe is a solid choice. Designed specifically for the 2015 and newer STIs, it gives you the flexibility to swap in a BOV from a different manufacturer. It’s a straightforward upgrade that can really change how your car performs and sounds.
One of the standout features is the stock flange, which makes it easy to fit right onto your existing setup. No need for complicated modifications—just bolt it on and you’re good to go. This pipe is compatible with Subaru STIs from 2015 all the way through 2021, so if you’re in that range, you’re in luck.
Just a heads up, though: this doesn’t come with a blow off valve itself. You’ll need to grab that separately, so pick one that suits your style and performance needs. Also, keep in mind that you’ll need the ETS piping kit to make everything work together smoothly. It’s a small extra step, but trust me, it’s worth it for the performance boost you'll get.
In short, if you’re ready to take your STI’s sound and performance to the next level, this blow off valve pipe is a great way to do it. Just make sure you’ve got everything you need to complete the install, and you’ll be set for an awesome driving experience.
