looking exhaust line

[SCP440]

Has anybody actually had an exhaust system or part of it rust through on one of these cars? The system on mine though a little rusty around some of the welds is still in good condition after all this time and close too 100k miles.

My guess it will be the catalysts that fail first or a lambda bung gets damaged removing a failed sensor.

Seems odd they used stainless on these cars but maybe there was a reason?

Steve, my back boxes have holes in them where the id plate is tack welded on. Could get a s/s set made up but it is the cats that will define the system and MGR ones (from Wilcox) will soon be NLA. Cats don't last forever so I've decided to replace the whole exhaust system with NOS MGR bits. If they last another 15 years then the system will probably survive my last breath.

Someone in MGR at some point in the past told me they were 419 and if they are not then they must be top class mild steel (might be galvanised mild steel?). 15 years for MS is very, very, very good.

Steve,

What is the life-span of a catalyst (yes, it will depend on usage and shorter journey's will produce more poison)?

How can one tell if they are at the end of their life (sulphur/rotten egg smell)?
