Happy New Year to you all.
I noticed this loose earlier and have now pulled it away as it has snapped. As I need the car tomorrow and have to drive 70 odd miles, can it be driven without one?
A bit stuck until garages open next week.
many thanks
Seb
 
Well, by pure coincidence Seb, I've just discovered that my nearside "˜muffler' strap has rusted away too - sounds to be in the same fashion as you describe.
I also don't know how secure this is either (exhaust not falling off) and was just about to investigate further, as I want to use the car on New Years Day.

If I find any info, I'll post on here, but let's hope someone gives us an answer soon[;)]
 
I drove mine for about 200+ miles before the Exhaust V-band clamp failed and the silencer dropped. It was a really quick fix and didn't fortunately cause any secondary damage. Without the silencer clamp, all the weight of the silencer is taken by the exhaust clamp just behind the rear bumper; It depends on the condition of that clamp and that it is torqued up sufficiently but not too tight to stress the bolt.
 
Thanks for the info... so you would say when the exhaust strap is not there doing it's job, the weight of the exhaust box is supported by the connection to to the silencer (behind the bumper) only?
Need to check the condition of this too, then[:)]
 

The silencers have a steel strip welded to the back of them that hooks on to a fixing on (I think) the chassis rail and that supports their weight. The straps loop round the silencers and pass through the rear of the "hook" on the car and as far as I am aware merely keep the silencers in position rather than actually support them. If the strap and one or both of the fixings have gone then the silencer is only supported by the end of the catalitic convertor. There's a fair weight in a 993 silencer and somethings going to give fairly quickly. I don't know about you but I wouldn't want a wayward silencer bouncing around the road under my car.

It should be pretty obvious whether the supports have gone by deeing if the sliencer will move up and down easily - don't use too much upwards force though or you'll push it off the hook [8|]

I personally wouldn't use the car other than to drive (carefully) to the garage to get it fixed or until I had fitted a new strap myself (it's not difficult) but I suppose that, provided the hook on the car and the associated fixing on the silencer are sound, and you avoid bumps in the road the car should be okay to use.

The strap I refer to is approx 3-4 inches wide and runs around the wide part of the exhaust. I can move the exhaust side to side but not up and down?!

I'm not sure we're talking about the same thing here Seb. The straps on the silencers of my car and all others that I have seen (including the spare ones in my garage that I bought cheap on ebay a couple of years back but haven't got round to fitting) are only about one inch wide. Without the strap there will be a bit of sideways movement as the silencer does not fit tight on the hanger on the car to allow a bit of fettling when connecting the silencer to the cat. As I said before the silencer is fairly heavy and is angled out so it may be a bit more effort is needed to move it up?

My mistake - it is about 1 inch wide so yes sounds like the same thing and from what i've read okay to drive ( i hope!).

 
A mechanic once showed me a trick of using jubilee clips linked in series ( straightforward stop-gap solution??[8|]:

- you 'un-do' the jubilee clips completely - then thread the end ofone into another - so bit like a daisy chain - this gave us a long enough strap to get aroudn a silencer and a suitlabe part of the car underside - to hold an exhaust in place for a weekend until time to get a proper strap fitted.

Might give you a bit of peace of mind while driving in the short-term?[&:]

Thanks for the tip, much appreciated.
 
As Clyde said , the strap holds the silencer to the support bracket, itself bolted to the camcarrier, The clamp connects it to the cat convertor. but the weight is supported on the welded lip hanging on the cam carrier bracket. If the cat clamp is in good order it would probably be ok for a while ,but if you put a jubilee clip around the silencer it will be safer for a month or two.
