Exhaust clamp removal

How easy is it to move the exhaust sleeve clamps?

Sometime soon I might have to take off my exhaust silencers (mufflers). To do so I will need to remove the sleeve clamp between the cat and the silencer.

The sleeve clamp nuts were very corroded, but came off without shearing the bolts. I had been spraying them with penetrating oil for a few weeks and I have now replaced them with new copper plated nuts.

It seems that the sleeve clamps have never been moved, though they are in good condition. Any tips on getting them moving? Heat perhaps? My experience of tackling sleeve clamps on other vehicles has generally resulted in destruction.

As for the silencers, I will try and undo the three nuts on the silencer bracket. If the studs shear off, and the silencer can be re-used, I will weld in new studs.

Thanks for reading.

Hi there

I just finished this job on my 2000 Carrera 4 last week. They were so corroded that i just ended up buying a new pair from Suncoast. I tried soaking them in oil, but quickly resorted to an angle grinder. Literally 5 minute job this way. And i could have reused the clamp and juust bought new bolts, but i wanted a shiny new clamp sleeve in the end.

Hope this helps.

I've always been able to twist them off without grinding/etc. I guess it depends on how badly rusted they are. To get them started, you can very gently tap them with a hammer to twist them or use some other form of leverage such as pry bar/etc. Don't pound on them too hard, because you don't want to damage the cats.
