Hello All,

  I am new to this forum.  I recently bought my 2004 Titan SE model 23kmiles.  I had the service engine soon light, which prompted me to go to the dealer.  They adviced that my CAT sensors were bad and would not cover any warranty due to after market headers.  They want me to put back original headers and pay for new sensors about $2,500.  Has anyone had any problems with these sensors?

tho its no supprise the dealer wont cover it, so i wouldnt try to make them do it
