It's not High Flow, or at least it didn't originally leave the factory as High Flow.I would like to find out if my 289D3 is high flow.
I gave the cat dealer the vin and they said there was no information about it. Any suggestions?
From the Serial Number it only takes a couple of minutes to figure out the answer.
There is no kit that I can see listed to convert your machine into a High Flow, which means that someone needs to get intimately acquainted with the Parts Manual to figure out what parts will be needed for the conversion.If it is not high flow can it be converted or is that not cost effective.
Attached a document showing how a High Flow Kit is installed on a 259D3, a machine similar to (but smaller than) yours, just to give you an idea of the work involved.
