they are basicaly a y adapter
they alow you to rout oyr exaust from source to this splitter. one end ov the splitter being capped shut the other end runing inline with the pipe to the muffler. now, if yo uuncap that one side, you have instant open exause where most of the exaust will exit that spot w/o entering your muffler.
