Intake and Exhaust Questions (upgrading) Options

[MyFirstCar]

I have a 94 GT and if I ever decide to do anything about increasing the performance, I will install an intake and exhaust system. But I have a couple of questions about both.

Intake: Are there intakes available to buy where I will not have to move anything in the engine to install it? And I see this term "forced induction," it that a type of Cold Air Intake or it that term related to a turbocharger? If anyone could give suggest a company to get it from (I was thinking K&N but it didn't seem they had any for my year celica). Or would it be better to get a SRI?

Exhaust: Say I was to get a cat-back exhaust system, what size should I get? Also, if i got a BIGGER exhaust, would it be a good idea to increase the size of the downpipe to that same size (if thats even possible) or should i just leave it alone?

Sorry for all the questions, but I am trying to learn as much as I can. Oh... and please don't give me any crap about how little horsepower i'll get. I'm doing it for the experience of working on my car. I was considering about using that honda accord intake but not sure whether I should try to mess with that.

I still passed here in Houston but they let you get away with 2 strikes on your test [3 strikes your out ]
It's gonna largely depend on the laws where you live. I'd check a local tuner site.
BTW - you can always install two carb legal high flow cats like Mgnaflow makes. Just make sure you position your two o2 sensors in the same place relative to the cats as they were stock. That should work just fine.
