Is this much smoke normal?
As you can see later in the video my engine is up to temp. The smoke doesn't have a smell but it seems like a lot more than my other cars and as you can see in the video there's water residue coming out of the exhaust pipe
I reckon it's not smoke but steam, from the condensation that builds up in the exhaust pipes when left overnight.
There are two small holes on the underside of the exhaust pipes, a bit before the muffler, and any build-up of condensation is meant to drip/drain out of those two holes.
Maybe your drain holes are clogged, easy enough to check.

Mine is doing the same thing, I'm thinking this is normal at this point. I might have to check out those drain holes tho. I did also just recently have my head gaskets replaced from excessive smoke on start ups. It's still smoking, but not as much as before... https://www.jaguarforums.com/forum/f...art-up-285773/
Water in the exhaust system…the (temporary) cure? A long, preferably fast, run to rid the system of the water. Short runs in which the system does not get fully heated will always produce this water.
I don't have my lift anymore, so will have to skinny under the rear end... any guidance as to the general location of these exhaust drain holes, so I can make sure they're not plugged?
Yes, saw those threads and did read that the weep hole is somewhere in the vicinity of the muffler. Will get the cardboard out and have a look.

Also, hope you know that the temp gauge is not accurate, JLR does not want owners running to dealers for every temp issue. So they run it up over a couple of minutes and it will stay there till the ecu detects an overheat and then will react causing said driver to overheat engine and then the driver to overheat.

I routinely monitor my coolant temp with the Torque app. The car temperature gauge reads at the middle at about 165F and to at least 210F. So it is not a good indicator of actual engine temperature - unless you think knowing the actual temp within a 45F range is good enough.
The steam is normal. Different cars produce different amounts, based on engine displacement, warm up RPM, exhaust thermal mass (how much steel there is to warm up) and exhaust surface area (how much cooling occurs)
Not challenging your statement at all. Was trying to reinforce your point. Sorry if there was any misunderstanding.
LOL, no worries. Have been stuck inside for a week from food poisoning and am getting paranoid and grumpy.
I remember that years ago I watched a Camaro start up an inclined driveway and I could not believe the amount of gushing water that came out if the exhaust pipes. Obviously his/her drain holes in the muffler were clogged, sometimes tge amount of water dan be quite dramatic.
See those black stains on the undersides of the joint pipes? Between the two pairs of nuts/bolts.
Then go to the forward most joins on each piece of pipe, and you will see a small half-moon shaped cut out/hole/gap on the edge of the join, that is the drain hole.
Not really a hole as such just a slight gap.
The black stains are dirty water dripping out of those holes and being blown rearwards and the dirty water is a mixture of condensation and exhaust soot.
