Very Mickey Mouse. Static voltages are high enough to bridge the surface corrosion on the exhaust stack. Get some proper bonding braid and high temp hardware if you are going to do this 'improvment'. Aircraft Spruce comes to mind as a supplier. BTW those bits of sheetmetal and stuff holding the push/pull cable needs replacement with Adel clamps/stand-offs/nut-bolts-washers positioned on the tubes and then there is the fretting wear on your strut fairing...a bit of trimming or adjustment of the cowl...
this all started badly with fly8ma using the continuity mode, not really appropriate for ESD testing. this mode can confirm only a low resistance circuit (under 50 ohms). Anything in the range of 1-2 MΩ or lower is absolutely fine for the purpose of dissipating a static charge. fly8ma probably knows this but decided to create a little controversy at our expense 😉
Boy are you (and Fly8MA) ever wrong!!! You don't need very low resistance (continuity as measured by a DVM) to bleed off static electricity from your airframe. Even if you have high resistance to ground (like a 100,000 ohms) you will quickly bleed off static electricity within a few seconds. (Just because you make a UA-cam video doesn't mean you are right.) P.S. Do yo have an FAA approved STC for that modification?

You are absolutely correct....
