165 Exhaust Manifold
Manifold cracked on the right hand side. These manifolds always seem to crack here
A professionally repaired manifold requires specialist attention...
Exhaust ports
The manifold surface is prone to warping, this manifold has been skimmed to get it flat again
Turbo flange - looks restrictive doesn't it?
Close up of the stock exhaust manifold outlet
With a little porting the exhaust manifold exit looks like it will flow better
This shows a 165 manifold being offered up to a 205 head...it won't fit!
Note
The 165 manifold is the only GT4 manifold with a 6 stud fixing arrangement
