Exhaust Question Options

[jimmykay]

OK, so I think I'm getting a small hole in my exhaust. And following my though of "upgrade it when it breaks" philosophy, I'm going to look into a a full system exhaust. I've been researching for a little while and I'm thinking about going with this set up.

surewin header
magnaflow high flow cat
vibrant ultra quiet resonator (unsure about length)
magnaflow muffler
All with 2.5" piping

Now, I know you get the header from ebay, but what about the rest of it? Is there a good site that I can order them from and take them to an exhaust shop to fab up, or should I just get them all from the shop?
Also, If I get them online somewhere, then what are the model numbers or part numbers that I'm looking for?

Also, I've read conflicting things about wrapping the header. Does it cause cracking? If so, is it worth it to send it out to get coated?

another question...

is there any difference in suppliers for the flex pipe for the exhaust? my thoughts are that a flex pipe is pretty much the same no matter which one I get. but I was looking around and most of them are around $30-40 and then I came across stainless works flex joints on jegs.com and they're going for $75. Am I right in thinking that is unnecessarily high?
