I really think it's a manufacturing fault in the Y tips. Thats the only place that has a sharp enough edge to create a whistle.

I cant get them hacked off now, cousin sold it. Oh well.
Think I will hold off and find a used muffler, not into the whole whistle tip thang. It has to be the y at the tips but do gruppe m mufflers have this problem?
