I was wondering why nobody has produced a stainless heat exchanger "kit" for 914's? I don't mean stainless heat exchangers like the ones that pop up now and then that were made in the past. I mean a kit that would use a separate upper and lower plate that would be held together with "cheese head" screws like the other heater system tin for 914's. Since it seems like a lot of the stock non-stainless metal ones are rusting away it would make it so anybody could cut off their old metal, bolt-on the new stainless halves and be set for life. I'm sure the pipes occasionally rust away but I've seen very few that had messed up exhaust pipes. Seems like it's usually the outers that are wasting away.

I'm also curious who made the stainless ones, how long ago and for how long? I'm sure the initial cost of tooling wouldn't be cheap but it seems like with all the messed-up ones floating around somebody could sell tons of them. They'd be a lot cheaper to ship than a complete heat exchanger as well.

@Mikey914 ? Maybe?

I would be first in line for these. I drive all year and have rusted out 2 or 3 sets of shells. My defroster really struggles to keep up with the freezing rain when the HE's are leaking.

I'm a little wary of the SS HE's and their ability to seal well against the copper crush gasket in the heads. They seem thin compared to the wider surface of the stock casting. In my little world a perfect HE would be the stock mild steel tubing, wrapped in SS shells for durability.
