Run the numbers John. For example:
Tracy is using a four inch pipe .035 wall about four feet long.
That is 603 square inches of SS. At .035 inches thick that is
21 cubic inches of SS. Stainless Steel has a density of .3 pounds
per cubic inch so Tracy's muffler weighs 6.33 pounds! A far cry from
a 25 pound turbo.

I understand the math theory, but I'd still like to see a real world weight
comparison. I'd be surprised if the weight all the component parts of an na
exhaust system came out at 6.33 pounds.

Well then double it and you are still half what a turbo weighs.
I am not knocking turbo's as I am using a turbo myself.
BTW I updated the ACRE NL web site and added a bunch of pictures
on my Kis Cruiser turbo 13B installation.
