Using this KA100 exhaust pipe is a breeze. First, decide which EGT sensor you want to use - the Big Nut Style or the 5mm External Thread Style. If you go for the Big Nut Style, you'll need to drill a small hole at the bottom of the pipe bung. For the 5mm External Thread Style, you'll have to grind or cut the bung down to the 'flat' and then drill the center. After drilling, sometimes you need to clean the threads with a 5mm tap. If you don't want to do these preparations yourself, just choose the pre - prep option from the dropdown menu, and it'll be ready when you receive it. When it comes to maintenance, regularly check the EGT bung for any signs of wear or damage. Also, keep an eye on the overall condition of the exhaust pipe. Remember, there's a freight fee because of the pipe's size, so plan your purchase accordingly.
