Center muffler is what the EPC calls the Resonator.
Besides the connecting pipes, the 112/113 exhaust systems have four catalytic converters, one resonator and one muffler. If you remove the resonator and the muffler as well as the rear cats, it will probably be pretty noisy. It's a well designed free-flowing system (if all is working correctly), and particularly so on the V6, so you're not going to gain any meaningful power.
The standard disclaimer applies, too: even if your location doesn't have smog checks, it is a civil and criminal violation of federal law to remove the cats. The odds of being caught are low, at least now, but as we get more greenies in government, that could change.
Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy; its inherent virtue is the equal sharing of misery. (Winston Churchill)
