( number of products: 1 )

Upgrade your BMW 4-Series G22 with a high-quality active exhaust system. Take full control of your exhaust tone using valvetronic technology — from quiet, refined cruising to an aggressive, motorsport-inspired roar.

BMW 4-Series G22 Active Exhaust – Redefine Your Driving Experience

The BMW 4-Series G22, launched in 2020, represents the second generation of BMW’s premium coupe lineup. Known for its striking design, advanced technology, and dynamic performance, the G22 offers an exhilarating driving experience across a variety of powertrains — from efficient four-cylinder engines to the powerful M440i and the extreme M4 Competition. However, the stock exhaust system prioritizes refinement and compliance, leaving performance and sound potential untapped. Upgrading to a BMW 4-Series G22 active exhaust system with valvetronic technology gives you total control over your car’s character — quiet and composed when needed, aggressive and sporty when desired.

Why Upgrade to a BMW 4-Series G22 Active Exhaust?

The OEM exhaust system restricts both exhaust flow and acoustic performance. A performance active exhaust delivers:

  • Valvetronic sound control – switch between quiet, comfortable driving and an aggressive, motorsport-inspired exhaust tone.
  • Dual personality – refined cruising with valves closed, exhilarating sound with valves open.
  • Improved performance – reduced backpressure unlocks hidden horsepower and sharper throttle response.
  • OEM-level integration – fully compatible with BMW’s factory electronics and driving modes.
  • Perfect for tuning – supports Stage 1, Stage 2, hybrid turbo builds, and ECU remaps.
