I have an 84 GT that is set up for drag only. Will I gain anything by adding an x-pipe and racing mufflers. I have heard open exhaust is best, but I also heard that the exhaust needs some back pressure and will gain hp if I have some sort of mufflers on it. Any advice on which way to go. The engine is a 351w and makes 450 horses at the flywheel. Not to mention my neighbor would like some exhaust on it.
