man , i just checked this today, i ordered them at work this morning, wish i would have checked here first! , why you selling them if i might ask? and are the easy to install?
Here is a pic of the header baffles from BCT that I used on my 09 RG with stock non-cat headpipe. Maybe the same as what you ordered, not sure.
I used them inconjunction with V&H basic slipons to quiet them down, but they also deepened the tone. BCT said I could pull out the baffle and just use these, but I would imagine they would be very loud. I pulled them off when I went with true duals and new mufflers.
Install was pretty easy, but I had to expand the end of the stock headpipe by like 1/16" of an inch for them to slip in. Some people file the edge slightly, but others the baffle just slide in. You have to drill a hole in the headpipe to secure the baffle with a screw.
Good luck.
I'll be posting these in the for sale section here soon.
