Mufflers? Maybe no gain. No more than 10 for the cat and mufflers together, and you may hate the sound.
3.4" pulley will add about 25hp.
Not sure about the chip.

Compare those mods to cars on CGP. You'll get a better idea there.

Add colder spark plugs to that list, and you will run anywhere from high 13'* to low 14'*, depending on weather, altitude, and driver.

Yes ... some GTP'* will run high 13'* with those mods.
