I have a 09 Ultra with the Jack Pot slip on pipes (2 yrs old). Performance is fine, but too mellow for me. I am looking hard at the new 4" Rinhart pipes as I like the large diameter with the new 180 rear's on the touring scooters. I just want to get it right. I want louder than the V&H Monsters, but not drag pipe loud. Can anyone help with this? I know the best way to find the right pipe is to go to a bike rally or bar, but I know I want louder than V&H MO, and large diameter without being a drag pipe........ Anyone recommend anything? Anyone try the Rinehart 4" slipn pipes? Thanks.
