182 Exhaust preservation

[mk1mark]

Hey folks,

I've just fitted a standard exhaust from the manifold back on my 182 - I've heard that these systems are prone to rot and have a lifespan of only a few years.

Will removing and painting the whole system with heatproof paint extend it's life dramatically?

If so, can anyone recommend me some paint?

No they rot from the inside out I’m afraid.
Engines kick out a lot of water when it’s cold.

The biggest issue is moisture internally from lack of effective heat cycling due to short journeys. Paint will to some effect help the exterior providing its suitable for the temperatures.
I do 50 miles a day and my original 182 exhaust was still plenty healthy after 70k miles and 8 years. So don’t discount their quality if kept moisture free.

Plenty of good run and heat help, we have a customer with a trophy that does 2miles a month and at MOTs the back box floods the workshop on cat test

Ok, that's great news as I don't really use the car often and when I do it gets plenty time to heat up.

Thanks folks!

2 miles a month lol.

I'd just walk and flog the car

Classic example of a car that will be sought after due to no doubt is super low miles yet will have more engine wear due to never properly being heat cycled.
