I didn't weld any pipe inside I just welded the box back up with the catalyst still inside.
The car feels smooth throughout the revs and pulls really strong all the way through as before it felt strangled and now its as though it has been allowed to breath and feels better than it ever has
In the uk our cars have an MOT inspection every 12 months (not sure if you know) and there is a visual inspection as if the car is produced with a dpf then it must still be in place to pass the mot that's why I went down the route of just cutting it out and welding back up also it saved me probably about £300
Our vehicle tax is calculated on the emissions the car produces when manufactured and as the dpf doesn't really affect the emissions (so im led to believe) it just collects soot so I don't think it should make a difference.

Is photo 1 of the inlet or exit? same question for photos 2 and 3

yes your right it is a fiddly job as my steering rack was in the way but im not sure that makes it the wrong side?? ive always been under the impression left hand steering was the wrong side

2nd and 3rd photos show stuff inside the can. Were both of these internal solids removed. Photo 3 looks like the filter material to me. Provided that is not stainless steel, I think i would be up to cutting the casing and removing the internals and rewelding back up. I have a MIG with shield gas. My trusty ryobi (basically a dremel) would do the cutting.

Between photos 2 and 3, which is the inlet and exit end?
