Solved. Went to lexus and they told me it was normal for is350s.
Basically high pressure fuel injection using direct injectors.

You can hear a bit of a knocking sound after start up. I have experienced similar knocking sounds like that when spark plugs were not torqued to specs and/or the wrong oil weight was used. You should have checked out by a mechanic to make sure it is not something serious - good luck.
