Speedfiend: DC Cycles sells those, also. Using one of those will give the first set of bend that I need but not the total effect.
Chilli: Nice site! Lots of beautiful pipes with both short and long versions of the peashooter available in 3 levels of quality to choose from. Their stuff is great but it's expensive and that's before you ad in the shipping to the US. They, regrettably, don't have what I need.
I think maybe using something like a doubled version of the "triumph bend", coupled with a short version of the peashooter might be the answer. I'm attaching a picture of the "new" Norton where you can clearly see that there is something like the Triumph bend coming off the header pipe, but then there is a distinct angled bend in the front part of the peashooter as it connects to the triumph bend. I'd try getting a pair from Norton but even if they would sell them to me, they would probably cost about $1200/pair.
We have a guy over on the xs650 forum, Gordon, who is a wizard with bending stainless steel. He makes several different styles of exhaust headers for our XS650s. If I can mock up an idea of what I need, he might be able to knock out a set for me that I could use with the short peashooters.
Thanks, guys, for your help and ideas!
