I have the RRM header and I really like it, makes the engine sound a lot more beefy. Only - is they don't come with a downpipe, the stock one does work just fine tho. There might be a few of them up for sale on the boards right now used. Rrm also has a CEL eliminator they sell for the header for 20 bucks.
Other options, heard good things about kamakazie, they come with header and downpipe. Or you always have your eBay ones, however I have heard of some fitment issues win the eBay ones. I would Go either rrm new for 320, or used for 150. It does delete the cat tho. You should be ok with passing a smog test with only 1 stock cat if your state does them. Just as long as they aren't to smart and fail you for an under the hood check. Just throw the heat shield back on for the inspection!
Good luck and enjoy your choice!

 

I like the kamakazie since i have one , comes with a big downpipe , have you seen how small the stock piping is on the stock one?

 

I suggest you search and read the FAQ.
