Anyone have a smoke machine?

I do. Used to have an auto repair shop.

Smoke machines help find vacuum and exhaust leaks, very valuable tools.

Just for grins, thought I would check my Audace. My dad has a 2014 California.

What a joke! Every slip joint on the bike was puking smoke. Smoke machines run low pressure too, can’t imagine what combustion pressures would do.

Long story short, this is why you get popping on the decel/overrun.
 
The loose fitting exhaust is only part of the popping issue.
The main issue is lean fueling from the factory.
 
What are the trailing throttle AFR readings? Almost every modern vehicles go from 16.0:1 to 20:0:1 (limit) during trailing throttle without popping.

Sounds like time for a GT-Rx ECU upgrade for you. That'll fix it.

It only has a slight crackle on low RPM decel. Actually sounds nice.

I’d love to see AFR readings before purchasing. My last bike was a RSV4 RF, a 2016. Conventional wisdom said that a remap or race ECU was necessary with a slip-on muffler. So I welded in bungs in the stock exhaust and the Arrow exhaust and ran my wideband in the real world. Both exhausts yielded identical readings under exact conditions (air temp, air density, route). Put a race ECU on, bike was super fat...12.0:1 all the time, cruise, full throttle, etc. The tuned ECU’s closely mimicked the stock ECU on the AFR table. Ignition was different.
 
What I was implying is that it's very hard to alter the air-fuel ratios for the various throttle openings/revs on the Magneti Marelli IAW 7SM ECU fitted to the Cali 1400. Obviously, Todd has the ability to do so, Rexxer is another possibility, although haven't heard many kind words said about the latter.
 
Yeah, I’m not a big fan of piggy-back systems. I wish I could write maps for this like I could for my V11 sport.

Todd's reflash is not a piggyback system. It is a new map.

Actually, my C14 system is a piggyback PC-V/AT-3 wideband. The fuel tables on the 7SM are cryptic, so I let the PC-V handle the fueling.

Like them or not, (facts are relevent, opinions are worthless), they work well and have proven stone reliable for me for 16+ years... and the product sits on the podium of most every AMA Pro event, and they have a Land Speed record in the 600cc class at Bonneville to name just a few.
I have them on every bike I personally own, and wish I could put them on the every bike I come in contact with. I won't debate that fact here, as it's a waste of my time as it was a decade and a half ago. Static ECU flashes using AFR data is decade old logic. Dynamic fueling is king.
My work on the C14 is well documented on this site; https://www.guzzitech.com/forums/threads/guzzitech-gt-rx-modded-cal-14-dyno-vs-stock.13773/
