CDi DPF tech question

Re: CDi DPF tech question

Removing the DPF, and the cat... and deleting the EGR (exhaust gas recirculation) you will be fine on a diesel.

You MPG will be a lot better too.

Sounds good... Can you tell us more about your replacement exhaust?

It was very cheap and its not loud. Just unbolted it, cut it open, removed everything, then put a spiral baffle in.

Re: CDi DPF tech question

Any idea how that will effect the tested emissions readings when the dreaded MOT comes around, as questioned by Ian Donkin - will it actually pass, do you reckon?
My 09 CDi is out of warranty in a couple of days - and I was thinking maybe a remap - but removing that lot sounds a bit severe for me!!

Mike - I now know you can get all the torque you could possibly wish for beyond say 2,200rpm with a remap and the DPF still in situ however I suspect the flow restrictions the DPF and cat cause prevent the turbo from spooling up at lower revs (and therefore keeps the powerband frustratingly narrow). More exploration to come for sure, but my DPF will be remaining for the next 11 months at least for warranty reasons.

Like you, I'd love to see some numbers on the emissions effect of a decat / DPF removal otherwise the exhaust solution has to invlove keeping the original for one day a year...
