Installing 5" Flo Pro exhaust straight pipe no bungs
 

Does anyone have any tips on removing the stock exhaust and installing 5" turbo back exhaust with no bungs? I have read that most people end up cutting as high as they can on the down pipe but i want to avoid doing this in case i need to put it back on someday. I also read that getting the hangers off of the frame is really hard. I've heard that there is a special tool you can buy to help with this. I will not have the truck on a lift when removing the exhaust and installing the new one with. Any advice would help i will also be receving my H&S tunner and cold air intake along with EGR delete kit.

Thanks
