Exhaust bolts seized

[AcID ZeR0]

Hi everyone, I need to decarbonize my exhaust but the bolts have seized the the allen heads holding the bracket have also seized on. The bike was made in 2001 and the exhaust has never been removed so you can imagine all the rust on them plus the first owner resprayed the whole zast pipe with black heatproof paint.

Is there anything good for unlocking the nuts? I've already drowned the poor sods on WD40 and some stuff called sealit bang or something my mum suggested.

Also what would be even better because I'm lazy is there anyway of decarbonizing the exhaust without removing it?

The problem being it's a snake bite exhaust meaning its at a very hard to get to angle.

Edit: what about a blow torch round the outside of it would that do anything?

You can either do the following;

1.) For a moment touch the bolt with a soldering iron to make the bolt expand a little bit fom the heat so as to break the rust.

or

2.) Use an impact driver with an appropriate allan key fitting while keeping the nut from moving as that will help to get it going.

sorry to hijack but its relevent...

When waveing a blo torch arround the bike... how likely is it that you could damage/warp the cyliner head, the studs afaik are just blank space behind, but the exhaust gasket would take up any warpage? any precautions?

got to do mine as well, just with less stud to move about
