Default Backfire, smoking after exhaust work

Well, I just tried replacing the headers on my '94 GT, but I bought the wrong headers for my car, so i ended up putting the stock ones back on.

Anyways, now when it idles it backfires every 10 or 15 seconds, and the headers and cats are smoking a whitish smoke, but it doesn't smell like steam. I can't hear any exhaust leaks, although I didn't replace the gaskets or anything when I did the work.

Any ideas? most likely an exhaust leak?

Figured it out. First two spark plug wires were switched.
