Hey guys
I'm having this issue that the yellow service engine soon light turns on after installing my catless dp. I running cobb stage 2 +st aggressive. Everything was working fine no light no codes but I went on vacation and the car wasn't used for 2 weeks. Today I turned it on and this light came on. However the car feels great no rough idle no rattle every runs smooth and I feel the power just this damn light is on im sure the o2sensors are installed right bc the car runs perfect but when I read the codes they say it's catalytic related. The car has 10k mls and I don't abuse it so it can't be any parts that needs to be replace. I clear the codes and it stays off the remaining time I'm driving but once I turn off the car and start it up again it comes on after 10min of driving My next solution is to buy bms dp fix and leave it on.

I searched for hours even went into other car forums that are running cobb but didn't find an answer. anyone have an idea what's wrong?

Standard issue with catless dp's

I'm not sure if he COBB has a code delete for it, if it doesn't grab the BMS dp fix as you alluded to

Problem solved!

Read the codes. U should not get post cat codes on stage 2, those are disabled.
