Like I said above retard, it depends on what the application calls for. Thats EXACTLY what I said, and you called it dumb!
And the same shit, Ill weigh some piping I have at home on a digital scale and tell you exactly what the difference is. Most cars have 3-4 feet worth of plumbing. I know for a fact, stainless isnt 1lb more per foot of equal dia/wall size than aluminum… so at most your theoretically gaining 3-4 lbs!!! no fucking way. if that’s the case, remove the paper work from your glove box and get that weight back!
