I know these turbos r supposed to be really quiet but mine on my 6.5 just screams, I can hear it over my exhaust and everything and I let my brother take the truck around the block and I heard the turbo before I seen the truck idk what's been done to.the truck to make it like that, its been that way since I bought it

 

what size is ur exhaust? do u have intake?

 

My exhaust is factory but its straight piped no cat no muffler and yes I have a factory intake
