In this thread I posted about my brand-new-from-the-dealer OEM exhaust manifold and catalytic converter. I've heard prices from $800 to $1000 for a replacement of this part from Hyundai. Just the manifold (separate, bolts on to the converter) like on my 98 parts car would have been $200+

Is it worth it to anyone who wants to go back to an all-stock exhaust, to trade their headers/cat/pipes/muffler setup, with O2 bungs in "won't throw a CEL" locations, for this, and/or the rest of my stock exhaust?
