Here's a question.... I have the BMW performance muffler. I was under the impression that the pipes have to be cut to install it, but Im really not sure. For me to get this would I have to do the stage 2? I am really confused by the whole cutting thing and am not sure if I can take the BMW perf muffler off and put another axle back in its place.
