I went back and opened that diagram again and listened to the pipes the guy had fixed up down under. Now those pipes sound AWESOME!!! Better than any I've heard in the product reviews forum. I'd love to know if they would accept pipes shipped to them from the US for modification... I think I'll send them a note asking.
