Temporary DPF Delete using Y-pipe?

Has anyone on here done a "temporary" DPF Delete using a y-pipe? I know guys with gas trucks did it to make their trucks louder or to use at the track.

Truck would look stock, and could be brought back to stock with the flip of a valve/switch, but I could also run it without the DPF when tuned as such.

If nobody has done this before, does anyone know what the diameter of the exhaust pipe is right before the DPF so that I can find a y-pipe that will fit?

I read a thread about someone else thinking about this, not sure if they ever did though. The stock exhaust is 3 1/2" after the downpipe

With a good welder, some pipe, bender, time and money you can do anything.

I was looking for a cost effective, manufactured, easy to install solution.

I looked into doing something like that. My only thought is that it doesn't do you any good in the warranty department. Despite stock exhaust still being on there, it's still evident that you've modified it.

I don't know that there is enough room before the DOC to even tap in to the exhaust to do it. The transmission cross-member is most likely in the way.
