I don't think the seller meant fair delete but PAIR delete. Basically it's a block off plate.. The port allows fresh air to enter the exhaust system at the exhaust port to help burn off otherwise unburnt fuel. While, on the surface it's a great idea for better exhaust emissions, it messes up the timing of the pressure waves traveling up and down the exhaust system so it makes for less effective scavenging and less power. So, you block off the port.
