So i did further research, they 2 brothers header outlet where the mid pipe mounts to is just under 2 inches. Anyone have any idea what pipes i can use with these? Also im probably going to have a hard time since these are not stock headers and most people are selling slip ons not pieces of a full system. Someone help please because i really like these headers and don;t want to sell to get stock headers with slip ons. See the damage is driving me nuts!!
