To the OP, with an $800 dollar budget you will easily be able to come in under the budget. If you want something that's going to be fairly quite at cruise but growl when you get on it, I would check out into a Chambered muffler such as a Thrush Welded or a Flowmaster. A word from the wise, you will experience cab drone with a good percentage of chambered mufflers. You could also look into a glasspack with a long case length (24"+), this would also possibly give you the exhaust note your after! As for headers, a good set of shorty headers will do the trick. I know Hooker will have scratch and dent models that can be had fairly cheap. Summits eBay store will have these from time to time.
Are you planning on running a set of high flow cats or reusing factory cats? If you plan on running aftermarket cats, that will eat up a good chunk of change in a hurry as will headers. Now if your planning on running true duals, I'd say go with 2.5" piping. You may also want to add an X or H pipe in there as well, they aren't 100% necessary but they sure do not hurt to have. Tips are just preference, but stainless is always a good idea for tips!
I'm putting in my mandatory hooker aerochamber muffler plug, because I believe they are gods gift to mufflers...
You need to elaborate on this muffler!! I've been interested in it since it debuted!
