Exhaust Systems

[starkizer]

I'm sure there are probably several other threads about this already. I did searches but didn't find quite what I was looking for.

 

I have holes in the down pipe, I don't have a cat but don't see any evidence that I ever did. All the pipe and hangers and everything seem to be where they should be.

 

So I'm looking at replacing everything from the exhaust header down. I have never done this and have questions. Everything appears to be bolted on, is this correct? I would like to add the cat back on. I assume I had one from the factory, but it sure doesn't look like it. Then my other question is, what mufflers will give me the best sound? I don't want something annoying, but I'd like a good growl if it's possible from a 4.0L.

I've found the pipe online for like 30 bucks each. So what else do I need? Gaskets? Hangers? Clamps? Any input would be great. Thanks all.
