The Rogue Engineering E46 DMS Exhaust is the original dual-muffler exhaust for your E46 3-Series. Designed and tested completely in-house by Rogue Engineering means that you're assured of great looks and sound, plus quality and fitment that you'll never need to worry about - all Rogue Engineering exhausts are produced from full T-304 stainless steel.

The DMS system is more than just a unique-looking exhaust system. The twin mufflers keep exhaust gases from the factory catalytic converter separate as they exit the exhaust when most aftermarket exhausts use a single muffler, which means the DMS system maintains the exhaust gas velocity from the cats by keeping them separate. Faster exiting exhaust gases means faster flow. Plus, the E46 DMS exhaust eliminates the factory center resonator to improve flow even further while adding an unmistakable sound.

The DMS exhaust has a louder and more powerful tone compared to other street-specific exhaust systems we have listed, so if you're wanting to be noticed, this is the system you want! 

Rogue Engineering has offered the unique look and sound of the DMS since 2001, and it's no wonder other competitors continue to try to replicate the success of the DMS with their V3, Gen 2, and many other versions as they try desperately to copy the unique features of this exhaust. Make no mistake, there is only one DMS exhaust for your E46.

  • Exclusive DMS (Dual Muffler System) high-flow design

  • Entire exhaust utilizes TIG-welded construction
  • Maintains BMW factory warranty
  • Rogue Engineering logo tastefully welded onto the top of the muffler
  • Can be clamped or welded (because factory exhaust must be cut, professional installation recommended)
