Take it to a shop and pay the hundred bucks. I tried swapping out just the hfc part (I have the active pipe) and it took way to long and is very difficult to work on your back. I'm assuming you have rhino ramps and the actual lift is only a little over 6 inches. If you still try, save yourself a day and get a friend to pass you tools. Getting in and out is a bitch! Quick tip: don't tighten anything until everything is in place and save the header tightening for last and do the part attached to the catback first. Happy DIYing!!
