Re: Exhaust Overhaul Questions
Most budget friendly is going to be factory dual exhaust. The flow won't be the best it could be, but it'll be far better than the single exhaust.
Also look for some performance mufflers. Most of them will be a little noisier than stock, but you can probably find something that'll be decently quiet.
If you live somewhere that doesn't do emissions testing, you can eliminate the catalytic converters, but on these cars they put oxygen sensors after the catalytics so that the computer could see how well they're working--if you eliminate them the computer will set off a code saying the cats aren't working properly. There's ways around the problem, but it can get expensive. And really, if the cats aren't plugged, they aren't a very significant restriction to flow. And they do help keep the car a lot quieter, which you said you wanted.
