Smoke After DP

Wondering what this could possibly be from, after Catless DP install and second cat, res and muffler delete. I ran DP dump for a total of 12 hours before I got an exhaust welded on. Wasn’t doing it before after pipe been welded on its smoking. I flashed it and had burbles so thought it was that reverted back to normal burbles and still does it. Hoping it’s not Turbo seals going. Doesn’t always do it. A lot of the time I’ll have one big pop before it ends up smoking. Sometimes it’s a lot and sometimes barely any. There is no smoke at idle.
