2. does bmw put up a fight with warranty claims with under drive pulleys?
1. The full Akrapovic EVO systems will trigger a CEL, a tune or delete-r module is needed to remedy this.

2. While BMW can theoretically challenge any aftermarket part vs warranty, I have not heard or seen any issues vs warranty denial being contributed to pulleys to date on the S65.

Most times, the dealer doesn't even notice them.
