WR250f 2007 modified muffler

I have a wr250f with all mods(grey wire, etc) with the oem muffler, which I think is terrible. A friend of mine has a Dr. D on his and he enjoys plenty of low to midrage. We took apart his DR.D muffler amd what we discovered is simplicity. A perforated steel tube running the lenght of the muffler, packed with muffler fiber and an endcap. I have all welding gear at home and am quite good at it. If I were to modify the WR OEM muffler as per DR.D mufffer length, perforated steel tube same lenght and diameter, and similar endcap, Would I get similar results. What other things should I consider whlile I have taken everything apart?

Thanks in advance for your help, Eddie.

yes,but it will be just as loud.

What if I wanted more low end ot the modified WR muffler? If I make the muffler shorter in lenght, would I gain more low end grunt?

Thanks again in advance, Eddie.
