Is there not a gasket from the manifold to the up pipe that connects to the y pipe on your turbo? what do you need to do if you have a leak? any advise would help thanks.

 

wait, what? which connection are you asking about? there is the exh manifold to up pipe connection, the up pipe to y collector connection, and the y pipe to turbo exhaust housing connection....

only the up pipe to y collector connection has a graphite "donut" in there for a seal...

 

Ok... Not sure what your asking so lets take it step by step...

Exhaust manifold to up pipe, nothing

Up pipe to Y pipe or collector, fiber gasket or Dougnut

Collector to turbo, nothing but a V-band connection

On the compressor side there is a small rubber O ring between the Y pipe and the turbo...

Hope this helps!
