Well, there's a lot of probes and tubes connected to this thing. Yikes. And you'll need to remove the passenger side motor mount bracket to get it out of its hole. And those probe connections take a lot of torque to get loose.

It would take a lot of work to create a replacement pipe that maintained all those connections. No wonder the Ecotune downpipe costs what it does. I see now why others are doing the cut-n-gut approach.

Had to remove parts 3 and 4, plus do some jaking of the engine, to get this out.

In hind sight I'd suggest leaving the DPF attached to the turbo/exhaust until after parts 3 and 4 are removed.

This thing is heavy.

Thanks for posting.
I wish there was more demand for 335d aftermarket parts, should be very possible to make an aftermarket delete pipe.

I think so too. There should be some movement on this in the near future ...

Just out of curiosity, how many people are interested in a US specific downpipe replacement?

is the dpf casing SS or mild steel? I'm wondering if my mig welder could reseal this up if i got info on how to gut it. I can't weld stainless steel. My Mig seteup has the C25 shield gas for nicer looking welds.

After the 100k warranty, Or sooner, I am ready for EGR flow reduction, dpf and scr delete. Of course the right tune to support this would be required.

Hmmm, don't actually know what metal it is. I do know that a magnet sticks VERY strong to the shell material. The silvery metal heat shield has a much lower magnetic property than the casing.

I would think the main shell is mild steel then. Not sure if the heat shield can be removed or if it is in the way for the gutting process. thanks tdi

I'm interested in a delete DPF pipe as long as we can tune it out.

He might be closer to this place and tuning option:

http://www.redlinespeedworx.com/specials/ecotune/

GreekboyD, I sent an email to the Canadian tuner you had mentioned in other threads, but never got a response. Are they still offering these tuning services for the D's? Or is it only for you Canadians?

TDIwyse, I'm assuming you're referring to Jarek at JR Auto? If so, I can also provide you with his cell.

I'm running with the Ecotune DPF removal pipe. It fits like a glove.
All sensors fits in it. In my opinion It's well worth the money.
Removing the filter was done my my local shop while I was looking. Removed from the bottom. Unmounting the right engine mount was needed to get it out. There was no room otherwise.
After having it mapped at BR-Performance in Belgium, who also coded EGR and filter regen out, the car really runs very smooth, and when needed pulls like a beast.
A 330dA with 321hp and 704nm is quite fast......

Just curious. How "smoky" is it now under full load?
