If the pipe is actually rusty then spraying a good dose of ACF50 and leaving it, as that is meant to actively neutralise rust ?‍♂️
I do this in the winter after a ride onto the collector box and the "balance tubes - seem to be a problem point winter because the bike is likely to be layed up for a few weeks but the problem is on the pipes it burns off. I get to my firts set of traffic lights and it looks like the bike is on fire with all the smoke  :lol

And why are stainless steel pipes rusting ?

My understanding is that they are made from a less expensive type of St Sl, and they take on a brownish, rusty looking tinge. Personally, Id never go anywhere near putting Harpic x10 on any bike of mine, for fear of getting it on other parts etc. Each to their own
