Kerker slip ons
Trying to get some quieter pipes. Have the SE Race only now. I know the Supertrapp SE and SE 65115-98B are the same but how about the Kerker 2 piece ? Looked on Supertrapp web site but they don't give much info on the Kerker.
The Kerker 128-78001 Double Espresso's have a smaller diameter core than the Kerker 128-78020 K3 cores(thelargest diameter core and the pipe that Joe Minton actually designed for Kerker, hence his continual endorsement in American Bagger
).......and the Supertrapp SE's(super elite's)have the smallest diameter of cores in comparison to all 3 of them. Looking at these pipes externally, they appear to be the same, again, the difference is the diameter of the internal core of each, which in turn would play a role in noise level.Sooooooooooooooo......depending on the backpressure your build would need, in collaboration with your tuner, is how the selection of any of these pipes are to be made if you are deciding on these for your bike. Got it?
