I've searched high and low as I'm trying to get spec ideas/options as I go through the build process over time... and I can't for the life of me find any aftermarket exhaust manifolds for the PTS. Trying to see if there is one available that will allow me to not only increase the size of turbo but also move from the internal wastegate to an external to have better control over the boost.

Anyone know of any out there? I've seen people hybrid stock turbos and upgrade internals, etc... but curious if anyone has yet swapped out all of these pieces.

 

Got my new Panamera technical book tonight and it looks like the manifold and turbo are manufactured as a single jnit so that could be why!

 

Did anybody had to change exaust manifolds gaskets? which way engine has to come out from the car for this purpose
