Thanks Red. Glad to see Yosh is on top of things with the new B1250. I like the carbon fiber.
I guess my thing with modifying the stock can is my stubborn frugal side showing.
I'm a decent fabricator, I have the equipment and tools to do it, and I can even build a whole exhaust from scratch if I wanted to put all the hours of painstaking labor into it. It's a balance of how much $$$ I want to spend versus the loss of riding time by building something.
A good compromise is modifying the existing components. For instance, I could buy a smaller diameter stainless or aluminum tube, use the existing internals out of the stock can with some fabricating, and come up with a good performance exhaust mod for under $50 bucks and about 10-20 hours of labor. And it would look good too.
It's a great sense of accomplishment... if I can get similar performance specs from the fruits of my own skills, and minimal investment. There's not that much "secret magic" when it comes to increased exhaust and intake flow... if you understand the principals. Of course it sure helps to have a dynamometer... I wish!
