Well im back again with more questions.
I just bought a mint powercore 4 muffler for a very cheap price off of a good friend of mine.
Sounds and looks awesome
What i would like to know is how much horsepower am i going to gain from it after i properly adjust my jets? (doing it tommorow)

I agree with you on the sound and all part. I have an old Titanium 4 from fmf but they stopped making them. It has a crack in and there was packing coming out due to the previous owner so i just wrapped it in some time of metal insulating wrap and the clamp is over it. I been told it sounds real good up at the drag races.
