how hard will it be to pass the sniffer test with a preformer rpm intake with a dummy egr on it. the egr only works when the engin is cold dosent it?

If you're reasonably tuned, no prob. I went through a couple years ago with the vacuum line plugged on mine and still ran so clean i dare say i could pass it without any of that crap on there at all. Actually, all of that emissions junk makes it run worse. Wish they'd let ya test without the visual. It's such a PITA to put all that on and take it off every couple years. As long as you can blow clean, who cares how ya do it!
