stopping exhaust before CAT.

What would be the down side of exhaust stopping before the cat. Would the down pipe give enough back pressure for the motor 2004 6.0.

back pressure is a misnomer for turboed vehicles...

it would be VERY loud in the cab and probably not legal anywhere if you wanted to put up with it

Aside from that, I can guarantee you would have exhaust in the cab. I stopped it a foot before the rear differential and turned it to the ground. IT BURNS DIRTY WITHOUT A CAT/MUFFLER and a HP tune...I can smell it sometimes. It is loud, your way would be annoying after a few minutes @ 2500 RPM.

Not trying to tell you what to do....but that is not a good idea.
