practical for a side exhaust to even come up as a mention as it isn't really too mainstream. I wrote the article to assist folks with those numbers that people seem to pull out of the air over all these years when someone asks "How much does X weigh?".
And actually I would have loved to do a weight comparo for the exhausts but there are just too damn many and exhausts are one of those things that folks love to argue and stress originality when considering a purchase. I didn't even want to go there. Tried to just make a nice universal VTF.
