mine weren't as bad as yours, granted, but they all came undone ok which surprised me as they didn't look as though they would.
i pre-warned my mechanic friend that i was going to be putting a socket
on them and asked about if it went wrong would i be in for a whole load of trouble? - he replied that it was not a problem if studs sheared.
i did liberally apply penetrating oil the day before, don't know how much difference it made.
good luck!
are you going to be cleaning / painting the front of the engine while the exhaust is off?
Re: downpipe nuts - ghostbiker - 08-10-11
I have seen worse.
I think the studs are pretty good and although the nuts maybe screwed up i bet the come out if care is taken.
pre treat with a REAL penertraiting oil for as long as you can... weeks if possable lol
but due to the angles of the studs i doubt it will have a huge effect. but every little helps.

i will give it a clean up when the pipes are off and a lick of paint,i have aqquired an exup asm off ebay but as this will take a few weeks to come (from the states) i will leave the downpipes on for a bit longer and give them a bit more soaking with penetrating fluid
Re: downpipe nuts - chitsu - 09-10-11
I took the rad off of one of mine that was almost the same as yours!
I wire brushed the excess rust off the nuts first & used 'DUCK OIL' which is an inexpensive penetrating oil that I have been using over 20 years now.
Female 'TORX' sockets are what I used to get a couple off as they were that corroded I could not get a standard metric sized 3/8's drive socket on them, but as has been said before ALL of them came off & the threads were fine.
P.S dont forget to clean the ports up with a small drill with a brush on as if it's not perfectly clean you will get a blow from the front pipes! (I learned the hard way : / )
Re: downpipe nuts - solorider - 11-10-11
as i have to buy new nuts i am looking at stainless steel nuts on ebay,i have found some dome nuts,i was thinking that they will stop the studs from rusting,do you think they will look ok?
Re: downpipe nuts - bludclot - 12-10-11
they will look the nuts! for sure.
they will have to be long enough to tighten the collars sufficiently before doming out as it were. they don't have a high torque rating (surprisingly and thankfully) only 15lbft.
what's the link? it's a brilliant idea that i'd like to copy blatently if you don't mind.

I changed mine for stainless dome nuts , got them from STAGONSET , they have a vast array of stainless fasteners , cheap and fast delivery . to ensure nuts didnt bottom out on tightening i used two stainless washers under each nut . hope this helps
they look loads better than the OE one's and protect the stus threads

Dont forget to put plenty of 'HIGH TEMP' anti seize paste/grease (not copper slip) on them or they will just seize up again!

Hi, I always thought Coppaslip WAS high temp grease. What is the difference, and what High temp paste do you use?

[/quote]Copaslip®Copaslip® (often misspelled as copperslip or coppaslip) - the original anti-seize compound. It is a very high temperature (up to 1100°C) anti-seize assembly compound, bentone based non-melt grease with copper, polybutene, and anti-corrosion additives.
Re: downpipe nuts - solorider - 13-10-11
i have bought some coma copper ease,it has a temperature range of -40 to +1150 degrees c so should be ideal for the exup valve,i have also bought some shock and unlock spray,it is suposed to be good for removing corroded nuts
