The AVO Up-Pipe incorporates a flex-joint similar to the OEM part, ensuring a tight fit and relieving stress on other components. This pipe also comes with mounting studs and a bung for the sensor.
Stock uppipes in most turbocharged Subaru models have a fairly restrictive catalytic converter, which has been known to fail, taking out the turbocharger with it. The AVO uppipe deletes the catalytic converter, which does make it illegal for on-road use. However, by removing the catalytic converter, two cats are left inside your downpipe. Removing the cat will also decrease your turbo spool time and increase your performance. This high quality product also comes with mounting studs and a bung for the sensor.
