cold air install question

[wheresmylicense]

it's done... i love it. the sound of the engine on the high rpms sort of changed, too, which i wasn't expecting... she breathes so much better now. what the hells up with the factory box n stuff? all that was doing was suffocating it!! the air had to like... go thru all these curves, and then there was one pipe that it could go thru that dead-ended... oh well, it's all done now... i had to keep it for when i go to get it smogged, though! anyway, now i gotz to get me an exhaust... how many of you people have done the custom piping and then just bought a muffler?
