Yet another Pipe question. I have an 04 Fatboy I had the dealership install SE II Slip Fits, install the SE stage I high flow kit, and also perform the download. I am now going to install a Hooker 2 into 1 tuned flow system. Will I have any issues by doing this? Or am I ready to run because I have already done it all?

Also I purchased these used, does anyone know where I can find some installation instructions?
