Those aren't actually the ones I have.
I've got these:

I'm NOT a fan of the headers with the hump, both because I don't like the look, and I don't want to have to deal with keeping the plug wires off of the primary.
I personally wouldn't pay $700+ for that system. Comparing it to the headers I've got, you're basically paying $400 for a catted Y pipe, with cats that personally I wouldn't trust to last. You can get some of the short Magnaflow cats from Summit for $100 each, then you've got $200 left over to pay an exhaust shop to modify the stock y pipe. I think the exhaust shop around here quoted me $100 to do the job, but I had a buddy help me out with it. Plus, you're getting some proven cats, not whateverthefWONk cats in the OBX system.
