Gettin ready to finish installing my exhaust system... but don't know what to do about my exhaust stacks being open for the rain to go in. The stacks are strait up but are cut at an angle. Any suggestions with dealing with rain water that will get inside there?? What do the semi's do? I was thinking about drilling a small hole either in the flex piping under the stacks, or putting one in the flowmaster muffler. Just afraid of it turning into a rust hole if i do that, and the ehxaust blowing out of the hole.
