The milk guide said to leave about an inch around on the diameter of the DPF, so that if someone taps on the can it doesn't sound hollow.
And it also said not to take too much off of the DOC because it will make the exhaust loud.

Is there any warning signs that would tip me off to whether I had a restricted exhaust flow?
