Regular price $1,499.00 USD

A full 304 stainless steel catback exhaust system with a variable valve controller for the BMW G20 320i and 330i. It opens up exhaust flow for a freer-breathing, better-sounding system, with valve control for sound on demand, aggressive when you want it and civil when you don't.

What it does

  • Frees up flow with a free-flowing design that reduces backpressure to unlock horsepower and torque.
  • Gives sound on demand through the electronic valve, switching between an aggressive note and quiet daily drivability.
  • Built to last from 304 stainless with polished interior welds and reinforced bellows to reduce vibration.
