I like the kroger bag mod.
Ok seriously, why do you want to blow smoke?
The diesel community is full of ignorant, irresponsible people (as are most other groups) but since ours can be very visible with all the coal rolling, it is getting a bad reputation. We are trying to fix it. With lots of power can come smoke, but just rolling coal without any power is honestly lame. I would love my truck to smoke too, but I want it to smoke while being able to outrun a Mustang GT or something very fast. If you DO smoke for the heck of it, do it away from city roads or lots of people where you'll just look like an idiot. On a back road, race track, or sled pull is more appropriate.
I'm giving you the benefit of the doubt right now. If you prove me wrong, you're gonna be screwed. Just saying. And not from just me.
