Idk what I'm gonna do yet..... basically the tight u bend will determine muffler design..... This is the bend I'm using.... it has a 2" bend radius so it should be exactly what I want....
I want to stay 2" ID. The stock pipe in the buell muffler is 1 7/8" all the way through.....the header collector is 2" so I want to stay at that size. I have seen many dyno results that a slip in baffle that goes smaller inside of a 2" drag pipe hurt overall performance so I dont want to do that. If I use a 2.25" pipe and a slip in baffle and go back down to a 2" pipe that should work pretty damn good. ID should still be 2" maybe 1 7/8" depending if baffles are louvers or perforated tube. This is something I'd look into using just making a bit larger case like 2.25" or 2.5" and packing and no packing..... I want that I pitched rasp gone.....
The guy at work has a Harley fat boy with a twin cam and boy it makes me a tad jealous the sound and note that comes out of those pipes...... just sounds absolutely amazing and its not that loud either. That's the sound I'm shooting for..... so far the short straight pipe is close just bit to loud
