mine smelled bad for a little while when i first put them in it smelled like burnt something but the smell when away after about a week or two as far as running bad it might be cause you don't have a tune but for mine i had an off road Y pipe too but i jad to get O2 spacers at that what i was told and after that it worked fine

gotta be careful sometimes when first running a new header there are oils and stuff that get burned off (more common with coated headers) but they could damage O2's make sure everythings plugged in. unplug your battery and let the computer reset itself if you havent already

Thats just the car telling you that you should of put long tube headers on lol. J/K
As stated above, the initial coating that burns off on the first heatcycle can kill the o2's. Unplug them see if it runs better. Also try resetting the pcm.
