it seems the truck kept the same size pipes for years, from 290 into the 600s...
the 500 in vid can explode things at 5 inch. it seems the past is catching up to old designs.
I have begged for a 3408 cat, dad says "they do not make them anymore".
I also have 30 years of trucking in at age 37... and I got alot to say, not exactly friend like either...
