Just for my own edification, does anyone know of any pictures or sketches that would show the internal design of my stock '04 500f muffler from a cut-away side view? Even a quick description (if pics aren't available) would help greatly.
Are you wanting to modify or gut the interior?
If no one else does...I have a couple of exhausts that I could cut one of the cans open, they are going to be cut off anyway.
Man.....I JUST threw one away. It's interesting to look inside - you can see why the exhaust is such a restriction. The entire exhaust flow has to pass through two nickel sized holes....
