HELP I bought an older DRD pipe for my 426, the guy I bought it from thought it would fit my stock head pipe.....wrong. I should have doe some research first but it was a good deal. So now I need a head pipe that will fit it. Dubach said they dont have one available any more, it an older round can system and they no longer make them. They had a few laying around but they sold the head pipes off them an only have the tail sections (go figure) Any help would be great.
