DPF Removal any experience are welcome to discus

Hi,

Does anyone have removed DPF for superb 1.9 TDI PD

Like:

1.9 TDI Superb S come without DPF filter GreenLine version have DPF

So if we use the exhaust part from model s 1.9 TDI so it is will be clean job like factory + we can read data CPU from factory 1.9 TDI and programme to GreenLine version 1.9 TDI

Just want to know aproximally prices and problems relating after removing DPF filter

Any discussion are welcome

Little help for discussion:

1 Why do we want to remove DPF (Use more fuel, load for engine and etc...)

2 DPF removed any warranty problems

3 Is it legal to remove DPF ?

4 MOT issues after DPF removed

5 CPU programming and cost

6 Can we put back DPF if legal requirement for MOT ?

Thanks
