Hi.
the video gives you a detailed step by step tutorial how to replace the exhaust system of your Porsche 911 G by a SSI exhaust system. For doing this the oil cooling system of you engine has to be modified, because the larger heat ecchangers are in conflict with an oil pipe. The video shows also this in detail.

The video has a German soundtrack, but English subtitles are available on YouTube. If you don't see them by defualt, watch the video directly on YouTube and enable the subtitles with the button below the frame.
Enjoy it,
Jürgen
