For the OP, what headers to go with. Come on man, it's 2013.
Cattman if you can find a set for a reasonable price. I've seen some FS lately and cringe at the mark up happening. I paid $590USD for used Gen I's back in late 2004.
If money is an issue, OBX's do the job. They might have a bit of a reputation for fitment issues and such, but IMO, the newest design looks fine to me and has been proven to be just as reliable and fitment has improved.
Shorty headers aren't worth the install time and effort. You're better off going with OBX's if you're trying to save a buck or 2.
Don't even entertain the idea of a y-pipe if you're looking for performance.

It's never been quantified, but it just seems like a better idea to get a set of headers vs gutting pre-cats, etc.

I went the obx route. The headers fit fine. No clearance issues with them. The worst part is getting old heat shields off, especially in the rear. The only "trouble" I had with the obx install was they wont fit if you tighten one manifold at a time. Put everything together hand tight before you snug everything up. Ive had them on for 5000 miles and havent had a single problem. So if your trying to save a little money, obx is worth it

I just finished putting my OBX headers up a few months ago. Only the only modifications needed on mine was the rear collector pipe was just touching the rear motor mount and I had to remove a bit from the mount to eliminate tapping. Also O2 sensor extending and relocating. Nothing major at all. Quite the easy install.

Ok sounds like obx is a good way to go if I wanna save a few bucks anyone knows of a good link to purchase them or just ebay? Also kind of off the topic but r intake spacers n bop a good idea or not worth it?

I grabbed my OBX headers from Ebay. Intake spacers are a great way to reduce intake temperatures. And the BOP opens up the intake flow quite a bit. You'll lose a little in the low end but gain in spades at the top. Also, the spacers I believe comes with a IACV coolant bypass which further drops temps with a bonus of eliminating the whole IACV shorting out the ECU issue.

I've seen heaters on carburetors before...but they use a venturi effect to pull fuel out of the float bowl. The pressure drop from the venturi can sometimes drop the temps enough to freeze the moisture in the air. Makes no sense on a throttle body.
