www.vividracing.com has a intake manifold made by Magnus that i was checking out for my 04sti. Does anyone have one on there Subie? I want to know how it performs and is it worth the money? Also is there anything you need done to your car performance wise before you install this manifold?

 

There was a guy that had one on an sti a year or so back. He said that for the money spent the outcome was dissapointing. If you search on here you can find his old post about it, or you could look on nasioc. Good luck
