I am certainly not wishing to mislead anyone
The OP has asked has anyone had a DPF removed and refitted - I have, and so have answered to the best of my ability.
I am afraid you are wrong - it is illegal to remove the DPF, eg. you may fail your MOT and you may be prosecuted under the regulations - it doesn't mean you will, but you are liable. I pointed this out as the reasons why I (I underlined I) decided to renew my DPF - you will also see that I said the OP might well have a different view, and that would be up to them.
Here is the source for my ***ertion that the removal of the DPF is illegal (the government) -
https://www.gov.uk/government/publications/diesel-particulate-filters-guidance-note
Here is the relevant passage:
" Legal requirements and the MoT test From February 2014 the inspection of the exhaust system carried out during the MoT test will include a check for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MoT failure. A vehicle might still pass the MoT visible smoke emissions test, which is primarily intended to identify vehicles that are in a very poor state of repair, whilst emitting illegal and harmful levels of fine exhaust particulate. It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use. The potential penalties for failing to comply 1 with Regulation 61a are fines of up to £1,000 for a car or £2,500 for a light goods vehicle".
Could you give a source for your ascertation that it is not illegal to remove the DPF and that with software manipulation it is OK? - where do you get that from?
If you modify your vehicle and don't tell your insurer (and I doubt that you will tell your insurer that you have made your vehicle illegal to drive on the road because you have removed your DPF), then, as we all know, your insurer would be delighted to refuse to cover you in the event of a claim because you have omitted to inform them of a modification.
So, I really don't see where i could be said to have been misleading
