Extreme Turbo Systems TurboSmart Flange Blow Off Valve Pipe Subaru STI 2008-2014
$225.00

If you’re looking to swap out your blow-off valve on your 2008-2014 Subaru STI, this replacement pipe is a solid choice. It’s designed to work with a TurboSmart BOV, giving you the flexibility to choose a different valve from another brand if you’re feeling adventurous. It’s a straightforward piece that makes the whole process a lot easier.

What You Get:

  • Blow Off Valve Flange: TurboSmart, so you know you’re getting quality.
  • AIT Bung + Plug: It’s included, which is a nice touch for those who want to keep their setup clean.

Compatibility:

  • Perfect fit for Subaru STI models from 2008 to 2014.

Keep in Mind:

  • This doesn’t come with a BOV—you're going to need to grab that separately.
  • You’ll also need the ETS piping kit to make everything fit just right.

This pipe is a great way to customize your setup and really get into the nitty-gritty of your STI’s performance. If you’re ready to take your ride to the next level, this piece is worth considering. Just make sure you’ve got the right parts to go along with it!
