Hmm...This is very interesting information.
I really look forward to get my downpipe fitted and get the car reampped once again after that :-)
But it makes me wonder....Aren't there any alternative solutions for the particle problem that doesn't have the negative sideeffect of the filter restraining the airflow in the exhaust?
How is the law in the UK? Is it illegal there to remove the DPF on cars that are fitted with this from the factory or?
I think it is here in Denmark and thats why I will keep my OEM downpipe to fit every second year at MOT test.
