Muffler & Tail Pipe questions

[CaptainStomp]

I have a 1994 Ranger XLT, with a 4.0 Liter V6 engine with the stock muffler and tail pipe. It's going to be needing replacing soon, due to corrosion, and I was wanted to get the best bang for the buck when I replace it. I was quoted $445.74 for the standard ford replacement and $320.00 for an aftermarket pipe and muffler. I would prefer to replace it with a good quality setup, that's made in the USA but will settle for something made elsewhere, as long as it's not China. I don't care what my truck sounds like, just as long as it's not loud, the quieter the better. I would like something that would boost the efficiency of the engine, yeah I know this usually increases with a less constrictive, noisier exhaust system, just as long as it's not too loud. I've seen prices under 100 and prices ranging up close to 1000. I'd like a setup under 300 but may go for one more expensive if it's worth it. Name brand is not an issue, just quality, efficiency, and as long as it's not made in China.
