I was wondering how to make my 90 Lincoln Town Car Sig. quiet, because It don't have any mufflers, what kind of mufflers can I use, I would like it to be quiet as possible...any suggestions?

Stock mufflers with the optional resonators. Any exhaust shop should be able to pick up the parts and weild them in.

So I can get a set from the junkyard, or a muffler shop?

What are resonators? how much are Resonators....thanks.
