Yup, 2k budget for power improvement will not get you much, maybe max 5-7% real HP increase at best via ECU remap or piggy back ECU if done properly.
If spending on exhaust, then it might yield even less than that, just usually more noise with just a tad better response but nothing significant. If want to improve the exhaust a bit, just remove the mid catalytic converter if have (but not the mid silencer/muffler), and then replace the rear muffler with local made Mugen style twin loop muffler, total should cost you just around rm300-400.
If I were you honestly with 2k budget, I'd focus first on the tires. That amount of money can already get very good high performance tires like Bridgestone RE003, Goodyear F1, Continental CSC5/3, Michelin PS3, Hankook V12 Evo 2, etc2 (assuming you're rim size is not bigger than 17'). It does not improve power but it will improve the car's handling, safety, and makes it more enjoyable to drive (again assuming if your car now not using such good tires yet).
