If not, buy egay headers ($150) and have a shop build a system for you ($300) and buy a decent muff ($100) and you're golden.
At least, thats what I did, and I'm happy.

That is a catalytic converter, but probably not a very good one. I don't run one at the moment as I have no emissions testing where I am.
Ryan is right, get the best deal on a header you can, and take it to a muffler shop and have them do up a 2.25" system and you're good. My whole system was about $500, but there was some custom work to do on the header.

does the modifying to the header just mean plugging a hole for the EGR valve??? cause if 2 headers and a downpipe come together, my only thought was that the downpipe length would be different.

The EGR hole can be plugged with a threaded plug. In my case, I'm not sure if it was the brand i bought or what but the front collector didn't line up with the Y-pipe and I had to have the flange cut off and rewelded. which he charged me an hour for.

the kit that I posted comes with a y-pipe i believe though so it should just bolt up to my catalytic converter.

Mind did too...it just didn't line up. the flange was clocked about 15º off.

Yes get headers, put them on yourself, then drive to the exhaust shop with open headers and get a 2.25 or 2.5 inch system made up using your existing cat converter.
Then when it's all done, take out the cat, and hollow out the inside so it becomes just a through pipe and you'll have a complete system.
I did my ZE swap, was running the stock intake and exhaust system at first...
Few months later, the exhaust blew out, needed to be done, so I did a 2.5" cat back (no resonator, magnaflow 4" skewed tip), but to think of it, I was probably running the stock cat, didn't really know better at the time. Car still ran a 14.7 that way.
A year or two later, put on headers (with new 02 sensors), stupid OBX/SS Autochrome ones that needed to be quite modified to fit. No wonder they passed through 2 previous owners and were never installed. Put in a test pipe since I had to have the car running for the weekend. Mx-3 was stupid loud, like STUPID LOUD.
Few months later the car was going in for body kit and paint, had planned to put a high-flow cat on her to make her legal since I knew she'd get attention after that. Got a ticket for loud exhaust 3 days before she went in. Car was there for over a month. First week I got her back, she went in and got a high-flow cat installed, quieted right down.
Coles Notes:
- ZE Swap
- Then Catback
- Then Headers
- Then Emissions Legal
Truck is going through the exact same process (minus the engine swap), just at Stage 2 of 3 for the exhaust. Exhaust was leaking in '11, so I did a 2.5" catback. Manifolds were cracked in '12, so I did headers. I guess I need a ticket first before I get the cats done, lol, but cats are probably going in this year since I'm hoping to be back in Ontario before Spring '14, and I'll need them then...
