I don't use the donut gasket, i have a wire mesh one. but just like anything that gets real hot
you need to replace it i guess.

I have not installed my Stembro yet on my '84 Westy but all this talk
about gaskets got me thinking why do you not use a stock OE gasket
upstream of the cat instead of a "donut" gasket?

Interesting, VW designed muffler brackets that don't crack regardless of
the vehicle they are installed on. (I admit, the Stebro ones would be
more elegant... if they worked!)

Frank, I have an email of yours from last year where you say you have to
change the gaskets every six months. SIX MONTHS! That's more often
than I change my oil.
- Has anything changed that you can go a year now? I'd like to know how
to double my gasket lifetime.
- Roughly how many KMs do your vanagons see between gaskets?
Another fun afternoon I had earlier this year: When I went to replace
one of the leaking exhaust gaskets, I found the nylon in some of the
1/2" locknuts supplied with the Stebro installation kit had welded
themselves to the bolts.
I had to break them to get them off. I have replaced the bolts at my
cost and inconvenience with M8 all metal locknuts and bolts.
Also, at some point one of my gaskets upstream of the cat self
destructed, and pieces got stuck in the cat where I didn't see them for
months. They sat there and gradually abraded a small chunk of the
ceramic away. Not cool - imagine what would have happened if I hadn't
looked in the cat!
Pictures? We got pictures.

Check out the threads on the bolts that didn't break and the condition
of what's left of the gasket.

Yup, That's a piece of gasket. I don't know exactly how long it was in
there but I'd estimate around 10,000 km.
