2024 Duramax Exhaust Tipping
2024 Duramax Exhaust Tipping. From what i can figure it's because when removing the old tip, the venturi device is. I cut off the ventilated exhaust tip and put on a mel’s 4 inch ventilated tip.
I’ve read that changing the exhaust tip on a 2024 will cause errors/codes. The next day it threw a p244b code.
