An X-Pipe Makes the E39 M5 Sound Absolutely Fantastic

This naturally aspirated V-8 is one of BMW's greatest hits.

The E39-generation BMW M5 is one of the greatest sport sedans on earth. It's the perfect mix of capability and luxury, all packed into a well-designed, understated package. Its main attraction is the S62 V-8 engine under the hood.

The engine's sound is fairly subdued from the factory, but install an aftermarket exhaust, and it really wakes up. The owner of this particular M5 has added Supersprint headers, an X-pipe, and Skytune rear mufflers. We can't get enough of it.
