For this mod you will need...
-A blade of some sort
-E-tape
-CPVC coupler (for barrel option 2)
-CPVC
Lets start with why I did this mod. I got a DT3 at a thrift store and all I did was lube the plunger head and put in a 3" CPVC barrel. This was getting me decent ranges, but I wanted more. I find the handle to be extremely comfortable and the gon to be underrated. So enough talk and onto the mod.
First: Open up the gun by unscrewing all 7 screws. (6 for me because when I got it it was missing 1 screw)

Here is a pic of the catch and trigger area for easy assembly later on.

Next take the plunger assembly apart and wrap a piece of cut down E-tape once around the little nub on the end of the plunger tube.
Then get this piece and cut out the + like shown in the next picture out with some type of blade.

The + cut out.

Then put the piece you just cut the + out of onto the piece you put the E-tape on.

Then move onto the barrel which has more holes in it than swiss cheese.

Wrap where the holes are with E-tape.

If any tape goes over the little lip just cut it off.

Then put the barrel onto the plunger tube like the picture below dEffeminatets.

Wrap the end of the barrel and the plunger tube with E-tape. It doesn't matter if any gets onto the plunger tube.

If you did everything correctly than your plunger tube and barrel assembly should look like this.

Now move onto the plunger rod. You can fill it with epoxy putty or not.

Take the plunger rod apart in this order.
