Cold air is more dense, so that makes perfect sense. Also, a turbo compresses the air, which heats it up, so you lose some of the power gains, which is why intercoolers are so common.
 
Not sure about the specific turbo, though.

Well first of all it's a Federal Offense to remove the Cat. I believe it's about a $10,000 fine or something.
 
As for HP and Sound, you can go for a high-flow cat and a cat back exhaust which will increase HP and Sound.

Fuel question by kabuji

Gooday all, I have a 2002 WRX that I'm in love with, ha ha. Only thing is, I'm havin some interesting fuel problems (I'm pretty sure anyway) and was wondering if any of you could help. My original problem was that it had trouble starting, I would have to crank it for a few seconds before it caught and started. The check engine light would come on and off, and eventually stayed on. I brought it into the dealership, they did a compression test and found that the #3 cylinder is firing low. They replaced the fuel pump, spark plugs, fuel lines and it seemed to work alright after this. (Luckily it was under an extended warranty, so the cost wasn't too bad!) Anyway, that seemed to fix most of the problem, but now it's kind of going back to the old problems, after only about a month or two. For about the past few weeks, the check engine light came back on, and it was hard to start, and now it's off and it's acting fine. Can anybody shed any light on this or if anybody has had anything similar happen?

If it failed a compression test, nothing they fixed addresses compression problems.
 
It's most likely the head gasket or the piston ring. Something is not sealing, basically.
 
Fuel pump, spark plugs, and fuel lines have no effect whatsoever on the compression.
