  1. Re: Hollowed out catalytic converter bad for engine?

    It could be. Did you check trouble codes on the ECU? Also check your EGR modulator/diaphragm to see if it's been overheated. If your EGR parts have been overheated/damaged by extreme heat, then it's...
  2. Re: Hollowed out catalytic converter bad for engine?

    Good question. I don't know which is better and/or the best value. For ease of installation I would go with a "direct fit" that already has the flanges welded to it. I got one years ago with flanges...

    Re: Full coolant flush tips?

    Re: Alternator woes
