Lamont and I took turns leading on our little trip home from New York. And one of the issues that I was worried about was the noise of his pipes. But with his little washer/bolt mod I thought the noise level when I was behind him was pretty close to stock. Not anywhere near that bothersome level that drag pipes can be. So if you are worried about noise and have the Cobra Dragsters make sure you find his mod and do that. It really sounds good.
