Any tips as to how to bring back the shine back on these factory exhausts? Have tried a combination of Autosol, WD40, ACF50 (though the latter not very relevant to the process) with Scotchbrite on the manifolds but the results are coming in very very slow.
Wouldn't sandpaper, howsoever fine the grit and lubricated in its application, leave a permanent scratched/coarse look on the exhaust though?
Yes. It does. I should havementioned, I've used 1000/1500 grit as a follow up and then the autosol after that. Autosol is actually quite rough too
I thought toilet cleaner was the Post 2010 way of doing these now. One treatment brings back the shine. Then Autosol to keep it nice. Not tried it but I think that's the common way now ?
Have been reading, and seeing (on YouTube), about the wonders of a one certain Harpic toilet cleaner (the 'magic' ingredient here being the 6% hydrochloric acid content) which appears to be much helpful, to a great extent, on stainless steel pipes (as are the factory ones). Think I will give it a try in open space during the weekend and see how it goes.
Some exhaust parts feature the blemishes unfortunately "in" the pipe, but I am considering the less intrusive options at this stage. Despite the preferred cleaning option, I'm certain that the bench grinder cannot be avoid in the end to achieve that factory original finish.
Well noted. I'm just trying to treat the neglected factory pipes before putting them in storage; homage to their long service. New shiny full 54mm Ti Termi's installed in replacement.

Proper polishing is the best (only) way to get a good, lasting shine/finish but be warned, it's a horrible, dirty job that'll take you forever to do. Or you could pay a pro to do it for you.
Scottish brite on a small orbital sander. Within a couple of hours, you can achieve a very uniform satin finish.
Harpic 10x stronger (or whatever it’s called) and then a brass bristle brush in the drill, scotchbrite then Autosol.
It's indeed the hydrochloric acid that does the work. Some brick cleaners have it up to 10 percent too and also work. Don't leave the stuff on for too long. It actually makes it worse as the stainless actually gets a rusty appearance if you do. I know, I did it.
