Need advice on my 6.4
i recently put a hand s mini maxx and took converter off, then straight piped it. i did not take the egr off yet and the other mourning i turned the key to see my oil light come on . So i checked the oil and it was full. decided to drive it to the dealer and only got 3 miles down the road till i realized i lost power and i looked back to tons of black smoke mixed with white smoke. I towed it home and havent drove since. does anyone know what it could be?? Do i just need to take my egr off??
