I am going to ask a question that, quite frankly, I am too embarassed to ask in person. What is the baffle on a 426 exhaust? I have the plug that it came with from the factory that fits on the end of the exhaust and the spark arrestor that fits inside the muffler. Are one of these also called a baffle? Sorry for my stupidity. Longtime rider, NOT a mechanic, but willing to learn.
