OEM VW vs pattern-part, exhaust heat exchangers & muffle

[NASkeet]

If you have ever wondered why, genuine VW exhaust heat exchangers, provide more heat to the heater & demister system, than pattern-part, exhaust heat exhangers, this cut-away cross-section of some specimens, featured in the following magazine article, should make the reasons more apparent:

Jim Tyler, "The Heat is On", VW Motoring, November 1998, pages 38~41.

The most commonly available pattern-part exhaust heat exchangers, seem to be those of the Dansk Autopart A/S brand, manufactured by J. P. Group, in Denmark. Other known manufacturers are Bosal Ltd. and Arvin Replacement Products Ltd., which both have divisions in Great Britain and possibly elsewhere.

Their contact details are:

I recently learned from one of my local VW Type 2 pals (less than 5 minutes walk down the road), that he has recently had severe problems with pattern-part exhaust heat exchangers, purchased from Just Kampers, for the 1976~78 VW 2000 Type 2 engine, of his Swedish specification, 1975 VW 1800 Type 2 army bus.

Several years ago, when I couldn't gain access to The Samba forums (restricted access at my public library), I posted details of various problems with pattern-part exhaust components, on the South African Air-Cooled VW forum, for which this is the link:

This includes transcripts of my correspondence with the managing director of Dansk Autopart A/S (aka J. P. Group, Jopex Division) in Denmark, BBC Watchdog, The Consumers’ Association – Which? Magazine and the Director General of The Association of Trading Standards Offices, based in Hadleigh, Essex, England.

I have yet to find the current contact details for Arvin Meritor, but here are those for Bosal:
