Smoke after Catless DP install

Hey guys,

I have a 2011 750li N63.
Has anyone had smoke of some sort after DP install? No sweet smell so I dont think it's a coolant leak. Its a variety of smoke it seems. One minute it looks like steam (white) and then the next it looks and smells like oil burning. Jb4 tune. No issues with smoke prior to install.

At initial start I did on my F10 M5 but it wasn't anything alarming. Definitely after DPs. Take a video if you can.

I had no smoke but of course my engine only has around 5k on it. Initially I was in the M5 forum and I saw some guys discussing seafoam as an alternative. May give it a shot. I'll get that video posted ASAP.

I have a set of VRSF catless dp s on my 2011 750 and no , no smoke after install or since here ..I also installed a oil cooler titanium valve from Sergey @ n63intakes.com ( https://n63intake.com/pages/rapid-se...rder=relevance) not sure if that has anything to do with it or not ... ohh and i'm also running a JB4 with 30/70 E85/91octane mix & carbon fiber intake with Burger tuning filters...
One thing I can tell you for sure though is that after I installed the oil cooler valve my car not only runs a LOT COOLER but it stopped burning the 1/4 quart of oil every couple of weeks ...so I highly recommend anyone with the N63 engine to get it ....
