If you are speaking of exhaust noise, repair your exhaust leaks. If you are speaking of engine noise, and it is loud enough that it bothers you, or sounds unnatural, the engine may be damaged internally. An inspection by a mechanic will tell you if your engine is making more noise than it should. regular maintenance such as a tune up and oil change will make your engine run smoother and will reduce noise.
