The shocks are not suprising an any way, the OEM ones were crap to begin with, and you have had them on for almost 8 years, I think that you got your money out of them.
For the rear sway bar, you dont need it to begin with. A lot of people just take them off.
when you talk of a hole in the muffler, are you talking abotu the little one that lets water drain out? Or you talking bout a big old rusted out hole in the side or bottom.
And since I have no ides what a wide pipe is, I will not coment on it.
