DO NOT PLUG THE HOLES. As mentioned before, these holes are for condensation. Unlike the stock pipes, the A & R Baffles are steel and will rust. I have two sets of stock pipes (modified, not modified) and both sets have the holes. Also, look at the position this holes are in, they blow directly into the tire's side contact patch. Maybe I'm reading too much into it, but looks like this holes were also design to help heat the tires.
