Title: Silencer slippage.
Post by: phil1 on 18 Aug 2022 at 13:02
Hi All
         Dare I say that my MKV is running very well at present So I decided on a short ride to our local farm shop to get something for lunch.
 On the way however I became aware of a sudden change in the exhaust note. So I pulled over to investigate, and saw that the silencer was slipping away from the exhaust. This is the second time that this has happened. Luckily I managed to retrieve the silencer from the last 1 inch of the exhaust pipe before the inevitable would have happened. What to do I thought!. Certainly it is food for thought.

I can't offer an answer but it might assist the experts if you say whether it has tubular silencers or a woffle box.

Not knowing the MkV personally, is there a clamp that can be tighter.
This is rather too obvious ?

Something I have used in such cases is something called 'muffler putty'.
This comes in a little tin, and is a thick gooey substance.
Once smeared onto a pipe or muffler joint and heated a bit, it sets like a rock.
And can 'glue' things together quite solidly.
(A rubber mallet can usually free it off)
Worth a suggestion ?

If it remains problematic, a self tapper drilled into a strategic location ?
Which does nothing for originality, but if its that or lose a muffler...

Hi where the silencer clamp is positioned slide this forward onto the exhaust pipe and then drill a suitable sized hole through the silencer front stub pipe and on through the exhaust pipe underneath it,then screw in a small countersunk screw,then finally pull the clamp back over the stub pipe ,this cover the screw head and keep the silencer in position.

Hi
         Thank you all for your responses. I have since found two holes as well as the three pinch slots under the silencer clamps, one of these I have used to drill through into the exhaust pipe, using a 2mm c/sunk self tapping screw to finally secure.
            With this in place I am now fairly confident of no more silencer slippage.  phil1.
