Sound test and installation for a Magnaflow catback exhaust. I installed it on a BMW e39. The magnaflow exhaust is much lighter than the factory exhaust and adds a much deeper sound. The quality of the exhaust is really good and is fully stainless steel. The clamps make the system easy to install and remove. Definitely a great option for the inline 6 equipped E39 5 series. If you only want to add a muffler I have linked the most common muffler used with the m54/m52 engines.
