How to remove exhaust?

Post by NZSpokes »

In the next few weeks I need to remove my exhaust headers. So I need to undo the nuts on the exhaust studs on the heads. I hear then snap very easily.

So am I best to put some oil on the studs for a week or two to work its way into the bolts, use some of the freeze spray or use heat?

Use a nut splitter to cut through the nuts on the front and then there is no risk of snapping the stud. Then once they are off you can clean the thread on the stud with a die and replace the nut.

But first I found it easier to grind the lip off the back of the nut with a dermal or you will be left with a little ring you can't get off , just take the lip down to just below the surface of the nut and it will split easier

Clearly this is a common problem. Is it only the front that has the issue?

Hitting the nut with a gas torch would not help?

The front gets the most weathered so rust's and seizes a lot easier than the rear. It's a risk attempting to undo a rusty nut. Some you win, some you loose. But if you loose you then enter the nightmare. So best to avoid altogether and sacrifice the nut for a new one.

Saying that though, a gas torch (heat) would certainly help. It has to be proper hot though. If you heat up around the base of the stud it will most likely take the nut off along with the stud as one piece. It wont help get the but of the stud but with the stud being steel and head being ally, a bit of expansion helps.

Advice just use the nut splitter or you will have to learn how to remove the front head which could be a good learning curve :D

I need to replace the rear exhaust (section from the head to the link pipes) and I'm not going anywhere near the nuts with anything other than a splitter. Question is, what size splitter do I need? Are they even sized? When I looked online a couple of weeks ago I couldn't work out whether the ones I saw would fit between the nut and the exhaust.

The nut if you measure it is 10mm - The smaller one in this 2 piece set handles 2-15mm nuts

Don't panic the rears are usually not to bad as they don't get all the shite off the wheel thrown on them. Give them a soak with plus gas or some such. Just don't use too much force when trying to turn them...
