Question for anyone that has installed Jardine exhaust

[GRR]

I recently picked up a really nice set of Jardine exhaust headers and mufflers. The problem I'm running into is that the collar that spaces out the exhaust flange seems to be too long for the stock exhaust studs. The result is that the stock nuts can't capture the threads on the studs.

Two options I see are to install the pipes without the copper gaskets, or to use special (Jardine?) recessed nuts, if such a thing was used. A third option would be to replace the studs with longer ones, which then might not work with the stock pipes if I ever went back.

Can anyone who has installed Jardine pipes tell me if you've encountered this , and if so, what you did?

Thanks, Gary

If it's just a tiny bit you need. Try re-installing the old pipes on the new gaskets but as soon as you compress the gaskets a little bit remove the exhaust and put on the Jardines and hopefully that will give you enough bite to get them started

Just a thought: Did you dig out the old gaskets before installing the new ones?

I found one or two crushed gaskets/orings thick stuck in my heads from my 1st IS which I parted out after my accident.

Very good point, I have changed exhaust before and found multiple crushed gaskets

The other option would be to take the exhaust down and place two nuts on the stud and back it out of the head a little bit.
I was surprised how far the stud actually goes into the head, on my interstate it is about an inch.
OR, you could get longer studs after backing the old ones out.

Thanks to everyone for the suggestions.

I continued to play with the right side until I was able to just capture the first thread of each stud. Having gotten that far, I decided to try the left side. Curiously, that side went a easier and each stud extended ~3mm past the flange, which allowed me to complete that side without trouble.

I went back to the right side and putting more upward pressure on the pipes, managed to carefully work each nut onto the stud sufficiently to seem secure. This was using the single original copper gasket in each hole.

My conclusion is that Jardine assumed owners would use the OEM Honda nuts, which should work as expected.  The deformation of my reused copper gaskets on the right side may have interfered. I'll replace with a new set of gaskets and see if that's any different.

BTW, I discovered removing the engine guards makes the task of swapping pipes a lot easier.

I had the same problem with my Jardines so chose not to use them for now .I do not recall special Jardines nuts and when called was told they never existed,no one there could help as to why the flanges were so thick .Both the tourer and the I/S were measured and I did not feel comfortable with only one or two turns on the header nuts.I am curious as to how long your setup will endure.
