you can get about any muffler from summit racing @ a decent price. It all depends on how loud you like your music if ya know what i mean. when you say manifold, I assume (using that term loosely) your talking about a header, only one readily available off the shelf is a pacesetter. run the pipes how ever you wish, just don't run them close to fuel or brake lines, or anything else (example spare tire) that you don't want to get hot.
note if you have to get emissions checks, you'll have to stick with the factory exhaust manifold, about all you can do then is hollow out the pre-cat attached to the manifold, and leave the pipe that it is connected to, then install a hi-flow cat & muffler along with the rest of the exhaust.
