there is no kit per say in what you are trying to achieve , you can pick up 2/ 12 mm plugs or or short bolts to plug the 12mm bungs , and 2 /18 mm welded bungs at any autopart store , you will need to locate and drill holes in the head pipes then weld the new 18mm bungs in at your new location, Ive done this on about 5 bike , and also have cut a few cats out and they are a pain in the butt to remove . if you can find 45% welded bungs they make the job easier to do , also rule of thumb o2 bungs with in 6 inches of exhaust port , I try to position them with in 4 inches of exhaust port myself. if you dont have avalibilty to weld ,local muffler shop will do for about 20 bucks.
