Also helps to reduce the soot stains on the back end.

 

with a DPF, the car should have no soot stains. It is a soot filter after all 

 

Any diesel car that belches black smoke probably has its DPF removed or is pre DPF

You still get smokey emissions though whether diesel or petrol. Emissions control isn’t 100%. Rub your finger inside the end of the exhaust if you think not.

I've did that and gone on to have my lunch time sandwiches.  No trace of soot on finger. My pipes are clean

 

For sure, very fine particulates are still being exhausted to the atmosphere. The filter has a minimum particulate size limit and cant completely block everything. But its barely detectable
