I dont understand. We already have full exahust as well and there is a definate difference in power :-\ Hmm...we're planning on doing an ECU upgrade anyways, so I guess we'll get there when we get there. Thanks for the help!!

So, we have an 03 WRX and picked up an Injen Intake off this guy we met and when we popped open the hood, we noticed all of these vacuum lines running to the stock intake, but no hook ups on the Injen one. Does anyone know what we're supposed to do with all those lines? We don't want to cap them off, so are we going to need to re-tap some fittings on the Injen?
