I want to install the BC Monster Baffles in my 09 vn900 SE. I want to keep the factory black pipes. I love the Size and look of them, but I am confused as to where to install the baffles. I know you should remove the stock baffles, but how about the Cat Converter? Should I remove the too? How far away from the cyl head should the baffles be if I put them in the header pipe? Has anyone done this yet?
