exhaust studs/bolts

[Wellington]

why do they use a set of studs and a set of bolts per head. Installing a bolt into aluminum and removing it makes no sense to me. The threads are expected to survive? With a nut exposed, you can always get it off, but a snapped bolt? Unless there is something I'm not seeing I'm going to install all studs with brass nuts to aid in future disassembly. Thanks for any insight.

One of the many dumb ideas that VW could of corrected in the engineering process.

I think it is interesting that Japan comes along and takes a dog and makes a race horse out of it

Usually such things have a good engineering reason; at the time. Could have been for assembly reasons or who knows what the Teutons had in mind. Remember these things are way past their intended service lives so all sorts of strange things begin to pop up (break.) After all this time, complaining does not help. Fit it or change it, if you do not like it.

What year do you have?
At least on the original exhausts on the 1.9l the pipes would not stretch to fit if studs were used all around, especially on #3.

Yeah, what he said. I think on some that it is hard to wrangle the exhaust into place if they are all studs.

Thanks for the input. Since I'm changing my exhaust on my 1.9, I thought i would intall studs now that the bolts are out. I'm putting the 2.1 factory system on the 1.9.
