In my efforts to get my Elantra as stock as possible, I’ve decided to ditch the 2.5" Mandrel bend and go back to the OEM configuration. I have a few options and wanted to share them to see what people think. I can get most of the parts from RockAuto.com minus the secondary catalytic converter for $321 shipped. At this point I would still need to weld a piece of piping where the catalytic converter is. If I went through Advance Auto Parts, I can get the same parts I need for $365.30 taxed, but will still have the same situation with the secondary catalytic converter. I did however find a local exhaust shop that stated they can install everything minus the secondary catalytic converter for $398.41 taxed. I’m at a fork in the road with what to do. Thoughts?
