Welcome to GMN! You can order a walker dual exhaust off the net for like $200. You could replace the mufflers with something louder if you like that. You can obviously go to a muffler shop and have them bend up your exhaust for you. when you do make sure you have some sort of crossover like a H or X pipe. The walker system comes with a H pipe.

I recently heard a 2001 Town Car with 2.5 Flowmaster Super 40's and an h-pipe; it sounded fucking evil! :evil:

If you want to make the most of your exhaust, have a shop bend you some 2.25" pipes. Or you can find a junked interceptor and take the dual system off that if it is in good shape.

Keep in mind there is very little you can do with a 92-95. There just isn't much available for those early 4.6's. To make the most power, you could do a full PI headswap, but that is not easy. A full PI swap is time consuming and can be expensive, unless of course you find a deal on a used heads/cams/intake combo and can do the work yourself.
