They said that with the 5-bolt turbo exhaust outlet and downpipe flange, there should just be metal-on-metal contact. That seems like a good place for an exhuast leak to me. Anyone know different? They don't list a gasket on their website, but they do have the internal wastegate (3-bolt), so maybe thats right. I tried searching on the web, but couldn't find any. This is what the flange looks like: I was trying to tighten one of the nuts when I first put it on with a homeade rubber gasket (bad idea, wasn't thinking there), and I guess the stud was so hot that it just snapped off. So it is stuck up inside. Any advice for getting it out...easy out? Hopefully 4/5 will seal it, but since there is possibly no gasket, that really worries me...thanks for the help.

Never use a gasket if you can do it without. Flat milled surfaces best for turbos

No gasket is needed

s4what?

The K04's come with a metal crush gasket - I sure will use it

They think gaskets are always needed.

Shame on them for not searching on info like that first.

Nothing wrong with a metal to metal surface as long as everything is torqued down correctly.

betwen the head and the header and that is only a thin steel gasket. I had the factory gasket wich was 3 layer gasket but they fellapart so Im using only one layer and I have no leeks, and I have been using that gasket since 1999. I dont even use gasket on my waste gate.

Get a new stud.

If you use a gasket it should be a stainless steel 3 layer one.

a gasket ... the list is a long one
Gotta say I wouldn't have tried a rubber gasket on the turbo tho ...

no gasket. Yup. Agreed with everyone else.
