You could also have you friend check out West Coast Pipe Repair I have heard some very good things about them, and for $50 it's a pretty good deal.

The stock Ti head pipe is really weak when it's hot. I'm on my 3rd one (actually went to a stainless one). The stainless one is a little heavier but I think it mellowed out the hit. The stainless header has a 2 mm smaller inside diameter (wall thickness is greater) with the same outside diameter. Maybe that is why the power is different. Anyway the stainless header is way tougher than the Ti.

I just had a nice dent removed from my Ti pipe by Pacific Crest Pipe Repair (www.piperepair.com).

The work was awesome, fast turnaround. $50 plus shipping
