Anyone know where to source out the flange for the dpf. Or know where a set of delete pipes are cheap.

 

Plate and a plasma cutter are all you need.

 

Ask Mr. Holmen. I believe he made the plate using the washer as a template. He might even make you the pipe, he offered to make me one but I wanted the 5" stainless so I saved up for it. Got a line on how to get 15% off on a exhaust if u r interested.
