Does anyone else have these degenerates where they are? You know the ones who modify diesel trucks to run too rich so the exhausts make big black clouds of smoke when they floor it?
I'm not a left wing nut, I do think the EPA has gone too far in many things, but this practice is just idiotic. It increases Nox and other toxic gases which are bad for people to breathe in. What's worse is the only reason they do it is to piss people off.
I really think anyone who does this should have their vehicle immediately towed, impounded, and license suspended until the vehicle's exhaust system is restored. On top of a hefty fine.
Same goes for cat deletes. I'm all about performance, but have you ever driven behind someone who's deleted theirs? You can barely breathe. Some things should just not be done.
Bigger turbos? More cylinders? Larger displacement? Clean, powerful noise? Yes to all of that. But engine and exhaust modifications that affect air quality adversely and unnecessarily I am not for one bit.
