Default 06 2.5i intake/exhaust options??

What would be the best intake (aircleaner/cone W/tube) and exhaust system(s) to install on my 06 2.5i non-turbo Impreza? I'm at about 8,600 ft in altitude and the factory setup is not allowing the car to breathe. Looking for some options that are not real radical, like superloud exhausts. Just something with a mellow burble that flows better/balanced and intake mods that would allow as much air as possible into the engine. Also, can this car be chipped?
Thanks for any responses!

This would be your best bet.
And no, don't bother buying a chip for your car. If anything, get a tune IF you do the hyrbid intake and put a catback on. Personally, I would recommend the "hybrid" intake it's the best option for our n/a. Search the stickies for the thread. You can fit basically any 02-07 Wrx/sti exhaust on, with a little bit of modifications from an exhaust shop. Just don't go over 2.5" diameter.

Oh and, welcome to the forums!

Axleback wise it is ok to go larger than 2.5" if you want that deeper tone because the muffler axleback portion doesn't really effect your cars performance much at all..just sound and looks. but recommend staying around 2.5" overall .My 3" turboxs axleback sounds great and i still have a hole lot of low end thump, but i feel the size difference kind of kills some of the rumble of my UEL Rallisport headers under a small load but wakes up and gives me a bit more of a push under a large load. If you go with a 3" full catback you would see some bogging issues and you dont want to do that but a 3" axleback shouldn't hurt anything if you do want a deeper tone. Hybrid intake is the way to go, gives you some noise and a push in the high end while retaining near stock MAF readings.
