Power trail for 3sge, mods? Options

[beno]

Hi

My mate brought a 1996 3sge celica and wants to know what he can do to get it more hp. Hes not worried about every inch of power though but wants to get pretty close to the max safe hp for his motor without changing the internals. It only has a ram cone filter at the moment.
He also wants to get the most power out of the car in the most efficient way (budget max is pretty much 2200USD), hes not keen on a beams swap though. Thatl cost to much right?

1) What are the options available?
2) Is there much hp gained from a complete exhaust from headers back compared to just removing the cat?
3) What about a computer? how much hp gain? what types the best? supporting mods that are needed?

So what have you guys done??

Thanks
Beno
