I just installed a new exhaust system on my 2004 Escape (from the cat back) and now I am getting a rotten egg smell from the exhaust. I didn't replace the cat; just the y-pipe back. Before the new exhaust the smell wasn't there. Any idea what caused it?

Its possible the cats are bad or you’re running rich. Did you buy pre made exhaust components? A lot of the time they have a slight oily coating to prevent rust. That could be burning off causing the smell.
