Very hard to believe, Unless they've been chipped..
The loss of the cat will let the VGT solenoid adjust the vanes on the turbo to build more boost, sooner. Thats it. And thats why we do it (as well as the cool sound :sweet ). Diesels do not need backpressure.
Yeah, No kidding! I'd be happy to get everything they (ford) took away from us.
You know:
Hood light
Hood blanket
Door lights
Double visors
Glove box light
rear fender skirts
Hmmm anything else.
Oh yeah, A quiet diesel with good mileage :roflmao
and get rid of that interior...
