just bought and installed the ss mbrp relocate kit, and was wondering what way does the muffler mount? kit installed super easy but the instructions dont tell you what direction to mount the muffler. it has one end with the fins that spiral and one end that they are straight. the fins or cups face out on both sides when looking in. prob dosent mater but i installed with spiral twords the back, a little louder than i thought but i am almost sitting on the muffler now. any imput??
