Removing resonator - there's going to be a droning sound. Removing muffler, well you get a louder system. These things are mainly for sound rather than any horsepower improvement. I can't imagine the sound in an Alza.

But honestly, if you really want a better pick - changing to a better air-intake + tuning would be best, and try looking up cat-back exhaust systems. However, it will be costly. There's also talk about back-pressure, but I don't think these cars are affected that much.
