An exhaust is always more than just a pipe. At a minimum, there is
also at least one muffler involved. On the 300SD, there is:
down pipe from turbo to first front muffler $134
front muffler with pipe $115
rear muffler $121
the down pipe is more expensive because it's two pieces with a funky
flex section that connects to the turbo. Considering that the volume
is declining for these parts today, I don't think the prices are bad
and am pleased that there are two aftermarket manufacturers still
making them.
