catalytic converter

I have just replaced the catalytic converter and the muffler on my 1992 Cadillac Deville. It now sounds like a sports car with duel mufflers. Why would it do this. It was not loud before I had these parts replaced.
Thank you.

Likely a cheap replacement muffler, unless they forgot to tighten something up and have an exhaust leak somewhere before the muffler.
