Also, never having installed a muffler before, would it be more worth my time and money to have it professionally installed?
A 3" diameter is too big on our cars. Go for a 2.5" inlet/outlet. This may have to be tweaked depending on the type of car you have.
What year is your Bonne? What flavor (i.e. SE, SSE, SLE, SSEi, GXP) is it?
Put this info in your sig for future reference so that it'* easier for people to help you get things figured out.
And, yes, get it installed at a shop.
