Vauxhall Meriva exhaust keeps breaking same place year after year

Not really familar with that particular car fault .Usually caused by engine mountings worn and allowing engine to kick .Call into any exhaust centre and ask for advice and if it is a common fault ? Wont cost anything for asking .

Stainless steel really isn't,
any guy who's been in a public urinal will be familiar with stains!
A better generic name is rustles steel so you do get a longer exhaust life from it.
BUT it isn't quite as forgiving as mild steel when it comes to stress.
I'd think it would give up even sooner than the standard pipe.
Welding another mount would be my choice,
so I'm wondering if your guy didn't rubber mount his fix?
I would have done.
And I'm wondering if Vaux are aware of this and maybe have a solution.
worth a call to your local dealers.

cheers both,my first thought was engine mounts gone but not the case it seems,stainless steel im not sure if its as forgiving as said and looking at the price id sooner pay £40.00 on ebay and replace it myself every damn year.the fitter didnt weld another bracket on just a 10/15cm solid round bar on top of the pipe then bent and welded on the back of back box to i guess limit play but still went,something which is making me think and it might be nonsense is when i hit 70mph on motorway the exhaust emissions light comes on after 10 mins of 70 and its always "exhaust gas recirculation prob",it might be faulty sensor but im thinking is the gas a little more restricted than usual causing the exhaust to heat up a little more than it should then going on the weakest spot,hence another reason i was thinking of a freeflow stainless might solve it.
its doing my head in got me puzzled guy said its a common fault on mariva but cant find anyone else with it ill have to do some more digging around i guess.
another mount welded on that to i was considering but it will be a last resort if i get no joy from vauxhall ect,and ill ask a few mechanic friends what they think,trouble is with that my mrs knows more than half of them just by watching and listening to me over the years and shes corrected them a few times lol.

I haven't heard of that problem either till you mentioned it .Possibly partially plugged cat or exhaust ?
