Cars these days are "computers on wheel", my recommendation is... if you want to mod a car, you better start learning to fix your own car first.
When you mod the car, you can't keep it to the same noise level either way. There will be some difference. My preferences are based on stability over power - caz you can have all the power you want, but if your tires, brake, suspension are not up the speed, there's no point having more power. What you are asking is very typical "newbie" question where more power is better, but that's not neccessary true.
My preference:
Wheel+tire, brake (pads+rotors), intake, exhaust, suspension (spring+shocks).
Keep this in mind, to gain another HP/Torque, you need to consider how much you are investing. You can easily spend thousands to gain additional 20HP, but with that you can probably buy another car that has more speed.
