On my GTS the oil pan is already baffled from Porsche. The problem it will have is the oil drain back from the heads. If you run at higher rpm too long the heads will fill with oil and end up starving the oil pump. They have an oil pan gasket that adds 1/2 inch to the oil pan depth that fixes the problem.

There are also some complicated systems with a separator setup to keep the crankcase vent from pushing oil into the intake. I just put a better baffle where the stock baffle is located. My intake is oil free. Originally thought that may have been my oil usage problem. That was until I found the there were some 928s Porsche did not drill the oil scaper ring groove hole that gives the oil someplace to go the oil scraper right takes off the cylinder walls.
