http://www.ebay.co.uk/itm/4t-ton-Exhaust-J...Sw4GVYHNCQ has anyone tried one of these just wondering if would be ok to use if needed to change wheels ???

In a word NO

Someone was talking about them a few years ago but I'm not sure on the outcome, there were concerns that it might not function with the twin pipe setup the ffrr has.. Plus actually getting to the exhaust on some L322's is a real mission  Yesterday I couldn't spell Engineer... Today I are one!

had one years ago on a series 2a worked great is there a major problem with just connecting to one exhaust ?

Only in as much as the system is not a true twin system, and the rear box has 2 pipes.. as the air bag needs pressure to inflate it, and one side of the box is open, there was a though "is there enough pressure" from what will effectively be a leaking exhaust... and then there is still the issue of getting at the bloody pipe to start with.. they have sort of hidden it up behind the rear wheel, not exactly use friendly..... Yesterday I couldn't spell Engineer...

I have one but I wouldn't use it to change a wheel. It's a recovery device when one is bogged. But as said above, the twin exhaust outlet could be an issue. I haven't tried it with the L322. Ron B. VK2OTC

Many many years ago someone here was going to experiment with lifting bags and using a plumbers pipe bung cut down to close off one of the pipes but I don't remember the outcome if any . 2008 MY Supercharged

I have a vague recollection of that one too.. Seeing as we are both in the dark.. I would assume that it wasn't successful ...........

The biggest problem with a plumbers pipe bung is they are made of rubber, and an exhaust gets Hot.... That is a recipe for disaster  Yesterday I couldn't spell Engineer... Today I are one!

We used to jam a potato into exhaust pipes for other reasons when I was a kid

Maybe that would work?
