Hey guys,

Swapping an OM617 turbo diesel into my '79 240D, and I don't want to spend money that I don't need to spend. Is the exhaust the same on the 240D vs the 300D? Clearly, the down pipe is different, but is the tubing size all the same? I would rather have a n exhaust shop weld up a new downpipe for my rather than change out the entire system, but I don't want to choke the turbodiesel.

Thanks
Max
