The pipes on my new-to-me America are just too loud... my ears are ringing. The pipes OD is 3" with little taper on the muffler section. The ID is about 2 7/8". I think the head pipes with heat shields are stock as there is a crossover between the head pipes. There is a reduction inside the muffler about 8 to 10 inches in; hard to measure exactly as they are slash cut but the reduction appears to be roughly 2". There is a hole in the muffler where a baffle once lived. There is no heat shield on the muffler part. I suspect the baffle was 8" or so. Anyone have an idea what type mufflers I own? Where can I buy some quiet baffles. HardKrome sells 3" baffles and I am not sure if that means they fit 3" OD or ID; I will check with them.
