I have a kenny brown unit sitting here. It is used but it comes with everything you need to install it.
It wouldn't work with my new 3.5 inch exhaust setup, so I had to remove it.
My buddy at the machine shop is going to do a bunch of these for a possible group purchase, we are working the details out now.
I'll let you know when he finishes the template of the KB unit and i'll sell you the KB unit if you like.
It might be a couple weeks if you can wait that long.
