After installation, what problems did I have?

I have had a few small problems, and one major one that I haven't fixed yet. My car will not pass emissions since I installed my headers, but I don't think it is because of the headers. I think I know I have a vacuum leak somewhere, and I think it is in one of the intake parts (manifold or collector).

I did have a few exhaust leaks that I had to deal with. The best thing for the simple leaks is just to go pay $50 to have them fixed. They might charge more if the leaks are at the headers. I had one small leak, that I fixed - I found this leak using a mirror and a flashlight. I took several pictures blindly until I got a decent one:

The driver's side and the rest of the passenger side look o.k., but I'll have to get it up on a lift to really check it out. I'm actually glad it was the pass side...much easier to get to overall.

I also had a lot of troubles getting rid of the leaks by the catylitic converter. I had to get a new cat and have a muffler shop do $50 of work for me.
