AWE Exhaust Suite for BMW G42 M240i: Performance Sound Meets B58 Power

16th Jul 2026

The BMW G42 M240i delivers impressive performance straight from the factory thanks to its powerful B58 turbocharged inline-six engine. However, for enthusiasts who want a more engaging driving experience, the factory exhaust leaves plenty of room for improvement.

The AWE Exhaust Suite for the BMW G42 M240i is designed to unlock the full character of the B58 engine with improved exhaust flow, dyno-proven performance gains, and a more aggressive exhaust note. Available in both Touring Edition and Track Edition, this premium cat-back exhaust system allows BMW owners to choose the perfect balance between refinement and maximum sound.

Built in the USA from premium T304L stainless steel, the AWE Exhaust Suite combines motorsport-inspired engineering with OEM-level fitment and durability.

Increased Performance Through Improved Exhaust Flow

The AWE Exhaust Suite replaces the restrictive factory exhaust system with a full 3-inch straight-through design, allowing exhaust gases to flow more efficiently.

Testing shows impressive improvements compared to the factory system:

  • Up to 65% increase in exhaust flow
  • Up to 10 wheel horsepower gain
  • Up to 17 lb-ft wheel torque gain
  • Improved throttle response
  • Enhanced turbocharged B58 performance

Even on factory ECU software, the AWE exhaust allows the engine to breathe more freely while providing the foundation for future performance upgrades.

Touring Edition: Aggressive Sound Without the Drone

For BMW owners who want a premium exhaust experience without sacrificing daily comfort, the AWE Touring Edition is the ideal choice.

Featuring AWE’s patented 180 Technology®, the Touring Edition uses specially engineered reflection chambers to eliminate unwanted exhaust frequencies inside the cabin.

The result is:

  • Deeper exhaust tone
  • Improved B58 character
  • Reduced cabin resonance
  • Comfortable highway cruising
  • Aggressive acceleration sound

The Touring Edition is perfect for drivers who use their M240i every day but still want a more exciting exhaust note when they open the throttle.

Track Edition: Maximum Volume and Aggressive B58 Sound

For enthusiasts looking for the most aggressive exhaust experience, the AWE Track Edition removes the 180 Technology® resonators to provide a louder and more raw exhaust character.

The Track Edition delivers:

  • Increased exhaust volume
  • More aggressive tone
  • Reduced system weight
  • Maximum straight-through airflow
  • Motorsport-inspired sound

This configuration is ideal for spirited street driving, performance builds, and enthusiasts who want the B58 engine to be heard.
