New member question
Hey, I'm new to the f-250. I have a 05 with 6.0.
My question is can I add a turbo back 4" exhaust with out the cat on. Will this hurt the motor of send a code. Thanks. Just trying to get the heat out fast.

5" in actually too big unless you are going to add bigger sticks. It will actually hurt your low end without enough back pressure. Most will recomend going 4" unless you are planing to go with bigger turbo and sticks. I went with the 5" myself, but only because I plan to add the big upgrades enventually, and I didn't want to have to redue my exhaust.
