The seams look way different than a DG to me. Looks like some hand coning by the mount too?

[Tri-Z 250]

Near the head pipe looks stock and the cone work isn't...the welds look a bit fat but in that area you'd want them to be. Post this pic and question in the Tri-Z Pipe ID thread...you might get a better responce, plus compairables. I vote homemade IMO, but nicely done. I wish there were a 2nd pick of the front of it. Could it be a rare race pipe? call the guy and ask what silencer it may of had. Might lead to an answer....
