So I was talking to another ST owner and we were both talking about the clacking noise our motor makes. Everyone says the injectors are the cause from the port injection. Any way to quiet these or upgrade to something less noisy?

The injectors sounding like a sewing machine is just a part of being direct injected

To my understanding, the high pressure fuel pump ("HPFP") generates more clackity noise than the injectors...

We have a DFI engine (Direct Fuel Injection), which normally are a bit noisier then EFI engines (Electronic Fuel Injection = Port Injection) hope this helps

My STs' injector noise is nothing compared to the wifes Equinox. That thing has always sounded like it's going to rattle apart!
