So I installed a set of BBK long tubes and an off road x pipe on my 2012 gt
last weekend. After a long ordeal with getting the o2 sensors working and getting rid of the trouble codes and the power loss that goes with that, the car runs great.
But, after it started running good, I started noticing a little white smoke coming from the exhaust at idle. Not to mention it still smells like its running kinda rich. Not quite as bad as when the o2s were freaking out but more than what I'd like.
Is this smoke normal for this exhaust set up? I'm running a Bama tune and oil level looks good and had mileage hasn't really changed. I was reading somewhere else on here that it could be condensation burning off and it's just made worse from not having cats but it does it all the time at idle only no matter how long I've driven it. Or it could be oil from the manufacturer in the pipes but I would think that it would've stopped by now after almost a week and plenty of highway driving. What do you guys think?
