In my opinion it wont give you enough to even notice but I may be wrong.

Ok any suggestions on getting started out? Just trying to get a little extra hp now but my ultimate goal is to supercharge it once i can afford it

one of the easiest way to gain a couple hp would be exhaust, headers, increase the diameter of the pipe from 2.25 to 2.5 or 3 inch pipe, and aftermarket highflow cat and muffler, just adding a muffler to the stock exhaust will do nothing but change the sound.
