Big fan of side exit headers here for all the reasons mentioned. NOT a fan of them coming out in front of the tire. It's just a LOOK thing for me, that's all. I realize in the rear can be tougher because of firewalls and inner fenders, but I would do the work to make them rear exit. Again just a personal opinion. Most cars have plenty of room behind the tire, it's just getting there can be an issue. Notch that firewall and floor......LOL!!! We even had to notch doors a little
