I have installed a ton of them, and it is a great upgrade over the stock airbox. 8-10hp has been proven on the dyno. I would do intake, then muffler, then chip in that order (ideally intake and muffler together, as you are shoving more air into the engine, and want to get it out just as quick to make your optimal power).
