Do you still have these?
I had to add a set of Street Rod Slashdowns to my bike to make room for a deeper set of bags. Figured I would add a set of Cobra Quiet Core Baffles to them after I got them to quiet them back down. 1 little problem, Cobra says they don't make them for these pipes. They have 2.25 OD and 1.875 OD available, and said my pipes are 2.125 ID, so being me I pulled the OEM baffles out to check. Yep 2.125 OD on the OEM baffles.
If these fit this configuration I will be happy to get them out of your way.
