Ok got my raw pipe today. When I went to install I had both header pipes on and then I ran into a problem. The Header coming from the front cylinder (closest to the handle bars) the heat shield is to tight on the pipe and I can not slide the muffler onto being the heat shield is touching it. Any way to do this? also the clamps on the headers are they there to keep the shield my moving and lastly are there no clamps to tighten the muffler to the header pipes? HELP ASAP. anything would be great!
