Replace stock cats with Magnaflows. Prepurchase on web...or find a local muffler shop who'll sell at online pricing (which would be better to avoid shipping fees).

Use AllenCorvetteStainless front Y-pipe. Maybe rear Y-pipe too.

Finish with no mufflers or glass packs.

Hard to get under $500. May be too loud w/o front or main converter. Mufflers aren't really any cheaper (expect glass packs).

Lots and lots and lots of threads on this topic.

Happy Holidays!

Leave the cats in place and throw on a set of eliminators. Just did that with my wife's 94 and has a nice sound.

Gregg has the right idea. There are alot of good mufflers out there that will work and can be put on by a good muffler shop.
