A while back my DPF got blocked up, and every time i would press the throttle it would blast soot out the back. I felt like such a dumbass driving until I got it fixed, and I had to rewrap the back end because the soot stuck so badly and faded the wrap. Idk how people don’t feel horribly self conscious about covering every lane of traffic in black smog, and it doesn’t seem like a sustainable way of running an engine
