Glad to hear your happy with it I can't wait for mine to arrive. Think I'm going to soak my bolts in wd40 overnight.
Clean what thread you can still see with a wire brush to .... believe me they snapped with no effort at all !!
Throw the can of WD40 in the bin, it is a lubricant. Go buy a tin of plus gas, the stuff is amazing, it penetrates down the threads. When you put it on rusty bolts you can see the rust run off the threads. 20 times better than WD. The head stud dilema will probably not be due to any kind of corrosion. They just get tight with the heating & cooling over time. Bandits & many other bikes are terrible for this problem.
https://www.mivv.com/en/moto/ducati-en/multistrada-1200-en/2010-2014-multistrada-1200-en/ MIVV do a range of different exhaust systems of various specifications and prices. So do you care to mention which one you are referring to?
I went for a I went for a Leo Vince decat and exhaust on my 2012, the build quality is brilliant, looks and sounds great. It also came with a thingy madjigy that stops the warning light coming on.
Ditch the exhaust valve servo motor altogether as well Exhaust servo eliminator module https://www.healtech-electronics.com/products/ese/ https://www.ducatiforum.co.uk/threads/exhaust-valve-servo-motor-removal.21359/
Well I've fitted mivv suono and decat today but only run it workshop....Christ it's noisy. The baffle in it is non existent has anyone fitted a proper one.
