Tough call on what the best exhaust for the money is. The exhaust that flows the best is the most expensive. The Jim Wolf Genie is a high quality exhaust for a pretty good price, but it's single tip on each side and it's an H-pipe. Greddy is also good. B&B is probably the most popular, but also the most costly. HKS also makes some good ones.
You should research your options and decide what's most important to you - do you want stainless steel? H-pipe or X-pipe? (Since you have an NA, this makes less of a difference.) Single or dual tip? There are many different styles for each and everyone likes something different. You can get a Monza exhaust for only $300 or so, but it's not stainless and it's pretty loud. Actually someone I know had one of those on his 1990 2+2.
Just look around... you shouldn't let anyone tell you what the "best" exhaust is for the price because some people have different reasons for buying what they did!
