EGR with reduced soot issues
This may have already been covered but I didn't see it.

Has anybody tried pulling the exhaust gas for the egr after the dpf filter?

Seems like it would eliminate a lot of problems related to soot.

it was a great idea, not really sure why it didn't work out, maybe someone will chime in that knows.

It did work out.

CAT got out of the game at the point where DEF fluid was introduced for whatever unknown reasons.

Wonder why that design wasn't adopted by the rest of the engine manufacturers.

I wonder what the cost to benefit ratio would be to fabricate a system on an existing truck?

altering the emissions system in any way is the same as a delete... even if it passes EPA standards.

the laws are written around the components/designs and not based on what comes out of the tail pipe.

==========

If you wanted to make an aftermarket egr or exhaust product that passes EPA then you will have to spend about $90,000 to have a lab set up a test bed + a $46,000 non-refundable submission fee to have a product review appointment scheduled at said lab... and then they usually do not approve on the first try... sometimes they will approve it on the 3'rd or 4'th try (costing the $46,000 submission fee each time) though if they like your idea. Otherwise, you could spend millions and they never approve of it.
