I got a flowmaster for my truck from the cat back for like 250. 40 series. It has a nice tone, and its a fair price. I got it from ebay, not sure if they are still available. If you go with ebay for the exhaust, I'd say about 300-350 bucks for everything.
Mine was 250-shipped...

Remaining smog legal doesn't have anything to do with the muffler selection (SI/SO, SI/DO) at all... Being "smog legal" has to do with the manifolds/headers, converters, and O2 sensors (and air pump if you live in CA).
As far as pricing, it can vary widely depending on brand, where you purchase, and whether you install yourself or have a shop do it.
Converters
Thunderbolt (http://www.performance-curve.com/index.asp?PageAction=VIEWPROD&ProdID=1181) (spun cat)- cheapest prices I've seen. Heard good reviews from several members.
Thunderbolt (http://www.performance-curve.com/index.asp?PageAction=VIEWPROD&ProdID=1060) (ceramic) - cheapest prices I've seen. Heard good reviews from several members.
Magnaflow/Car-sound (http://www.performance-curve.com/index.asp?PageAction=VIEWPROD&ProdID=396) - same distributor as the two above, seem to have the cheapest prices regardless of converter they carry. Good reviews from many members.
Random Technology (http://www.randomtechnology.com/) - creme of the crop quality based on member reviews. Pricier than other cats I've seen. Must be ordered from RT or one of their distributors.
Mufflers
Ask 10 people, get 10 different answers.... very subjective. Generally speaking, if you want performance, go with a straight through design (no baffles/chambers). If looking for sound only, chambered mufflers are hard to beat. Longer case length will produce a quieter, but deeper note. Shorter case length will produce a louder, but raspier note.
I've had Flowmaster (DeltaFlow 50/SUV) and now have Magnaflow (5x11x22 case). Both are louder and deeper than stock. The Magnaflow is a bit quieter overall and definitely at cruise than the DeltaFlow. I've also noticed an improvement in acceleration, cruise, and economy with it as well.
Piping - Generally, price will depend on your location. That said:
3" will cost more than 2" or 2.5".
SS will cost more than aluminized.
Mandrel bending will cost more than crimp bending.
