While the picture sure looks nice, in my experience, pacesetter makes the lowest, worst, most horrible quality exhaust on the planet. I also think it will be an extremely tight fit to get a dual out into the space over the rear axle, and I imagine the rear pipe will constantly clang againt the sway bar endlink.
My suggestion would be to get a Dynomax catback instead. They make a kit just for the 91-92 Sport that bolts right on, 2 1/4" with a Super Turbo or Ultra Flo muffler. Get it at a parts store like Advance, and bolt it all on yourself, no welding required.
The 2 door exhausts are supposed to be the same as the 4 door with just a shorter pipe from the cat to the muffler, but I tried shortening the pipe on a 4 door exhaust to fit my sport before and it sure didn't fit at all. Fit a 4 door just fine. There also seems to be slight differences in the exhaust for a 91-92 and a 93-94, so be sure whichever exhaust you choose, it's for a 91-92, less hassle.
