Hi LIL J two good reasons to leave well alone the warranty becomes null and void and you are more likely to get a ticket if the exhaust is noisy. then we have the other issues like poor acceleration and reduced mpg. so what is the point of any modifications if it has a component failure BMW will not honour the warranty. so you could be paying out for something which is nothing to do with making the exhaust louder. then the police will fine you for being an idiot. the lack of what that particular car is famous for acceleration and top speed what a dummy you will make of yourself.
