How much horsepower will this gain you!? Probably none, but it does give you the benefit of hearing the factory bypass valve and a slight induction noise as the turbo sucks in the air. The factory air box is also good up to 400 horsepower, so this gives you induction noise you crave while leaving your pocket book alone.

Time frame

This most difficult part of this modification will be either removing the front bumper or right front inner fender well. SG forester bumpers aren’t held on by many clips so for me this takes around 20 minutes max. Give yourself additional time if your bumper has never been removed or your clips are seized up with dust and dirt. Forty five minutes to an hour is a very realistic for those who haven’t attempted this before

Tools

The tools necessary to today’s job will be removing the couple of bolts that hold the resonator in. My favorite ratchets and sockets will help get this done.
