The hp gains will be EXTREMELY minimal if you just remove the silencer stuff....BUT...it will make the engine sound a little more bad ass.

Honestly (not a technical type dude here) I would say go for it, just don't wreck 'em 'cause if you need to have the car smogged it would be good to keep all the stock type stuff.

a good first intake is to remove all the piping from that black box...then go to Home Depot (hardware store, and DIY paradise) and get some sort of tubing to run the intake from that box to the side of the car, into the fender. You will get a little HP out of that...more than anything it will rev up quicker. Larry Ganz has an intake that does just that, and if you go to his website you can see pictures of what he did. His system is great, but you can do a rather more basic one if you use his pictures as a sort of blueprint.

Good luck with your first DIY intake!

Of course, this is only if you have a 2000 or up Impreza.
