does it sound normal?

[NothernVAMustang]

I feel like there is a bubbling sound coming from the exhaust and I'm not sure if the engine sounds normal. This is the first time I ever owned a mustang. I have the Roush intake and Ford racing sport cutback installed. Let me know what you guys think about the engine sound.

Direct injection working and VVT. Sounds totally normal. Don't freak out man!!

So that's not considered knocking sound?

The injectors for direct injected applications are much louder than normal fuel injection. It's totally normal.

Sounds normal to me. The HPFP (high pressure fuel pump) is cranking out some serious pressures to those injectors.

I'm confused.... is it loud in my case the direct injection or in general?

 

[KazyMedic]

Direct injection is loud in general
