ok im wondering if anyone has cut open or will cut open there stock rear section of there exhaust. a buddy of mine found a way to cut up his stock gsxr600 muffler and it sounds relly nice and was free at that. i figured there has to be some way to do the same to the 06 636. if anyone can post some pics of the inside of the stocker it would be great or exsplane what to do. also welding is no problem so if it requires cutting and welding let me here it. thanks.
