Been thinking alot lately about making a megaphone slip-on for my bike so that people can hear me because we all know people here motorcycles before they see them. I have a factory cat on my bike and my stock muffler bolts to that. I am planning on making a straight pipe to come right off the cat and do away with the muffler. I know there wont be any power gains and thats honestly not what I am looking for anyways. Will it have any negative affect on my motor running my bike without a muffler, just a pipe in it's place after the factory cat?
