How long until it arrives?

No, Fabspeed engineers them for no catalyst-related check engine light.
How much power do they add?

Will my Bentayga sound louder?

Which option should I choose?
Check under your Bentayga for gas particulate filters (GPF) before ordering. European-spec V8s often have them fitted, US-spec typically doesn't, and choosing the wrong option means the cats won't bolt up correctly.
