will they make our trucks sound better????????

 

I just got off the phone with JBA,I live by the company in san diego. They said they have not even tested these headers "we have not even tried to bolt on to a f150 4.2 to see if they fit".. - but they are takeing orders.
I ask him if i would be able to return the headers in case my truck turns into a dog. ______________JBA had no answer.
