borla plates
#4
I just made my own. I had the one plate but it was still a little too loud for my neighborhood. I just picked up so sheet metal and used the one plate that I had for a template and cut out a new one. You can of course make your own size hole for the middle of the plate. The piece of sheet metal cost me $5 and can get at least 3 plates out of it. I will be putting a cut out in its place eventually though too.
