You're quite right. The Sports DPF could be significantly more expensive.
My one slight concern about DPF removal is future MOTs - not a concern at the moment as my first one will be 2015. If they start measuring particulate emissions won't a car without DPF fail?
Excellent point. My understanding was that with correct mapping, the car would be at least as clean. Maybe GAD can comment further on this, doubtless many of their customers have passed MOT's post DPF removal. However, if things tighten up further there might be issues.
My Impreza was de-catted years ago, yet, as it was properly tuned, still just passed the emissions test - it was below the maximum permissable for that car of that year, basically bang on the manufacturers estimates. However, a few years back they tightened up the limits and restrospectively applied it to much older cars. As a result, my cars target was BELOW the manufacturers limits. Needed to add a sport cat at that point.
So, we do need to understand this fully, as future regulation changes could impact things. It may be that without a DPF / with a Sports DPF that particulates are within limits, but it might not be possible to meet future, tighter limits.
My gut feeling is that w'd be fine without a DPF come MoT time, but I might be wrong.
