This is the first time I've ever heard of an FE being installed in a BDR.
Interesting comment that they couldn't find an FE in SA, not surprising I guess when you think about it. What a nightmare the installation must be!
I would highly recommend the Rem Flex soild graphite exhaust gaskets. There pricey but they are the ONLY exhaust gaskets I've found that gave a perfect and LASTING seal on my FE. Man I spent some money and some time on various exhaust gaskets before I found Rem Flex. I even tried the all copper high dollar gaskets, those eventually leaked as well. Here's a link:
