Ajax - I'd recommend the Flowmaster Force 11 system which has a 2.5" center pipe and 2.25" mufflers. You can get it from people like Summit Racing as well as SCP. Plan on buying the cat-back kit for about $280, plus you'll also need their corresponding resonator for about $115. It fis like a glove and very easy to install, just cut the stock downpipes off. All the clamps & hangers are included. Sounds a little deeper than stock and should be good for modest mods, say up to 275-300 hp. I've had them on both my '93 - 5 speed and '94 auto. They last about 5 years or so. Only drawback is you can't just buy replacement mufflers - you have to buy the rear kit (2 mufflers, rear Y pipe & center pipe). Also tried to skip installing the resonator, but it's way to loud inside the car.
Good luck.
