One thing to note when plunking money down on exhaust is that not all stainless exhausts are created equal, and a lot of manufacturers purposely do not tell you which, in their product pages. 304 is significantly more corrosion-resistant than the other common exhaust material, 409 "stainless". 409 is frequently compared to regular old aluminized steel with apparently parity.
Fit is hard on these cars, in my experience. You get the location of the main muffler strap off by half an inch, and the whole exhaust won't fit at all, or will hit the axle, or hang really low! The angles are critical.
It's gotten to the point where you could purchase a cheap fluxcore welder and some pipes and bends and clamps, and make a stainless exhaust for the same price as a shop would charge to make one. If you have time and space, I'd recommend going this route. You'll learn welding, too!
