 Why Upgrade to High-Flow Downpipes?

•  Increases Horsepower & Torque – Gains of 20HP+ with proper tuning

•  Improves Turbo Response – Reduces backpressure & allows faster turbo spool

•  More Aggressive Exhaust Sound – Louder & deeper exhaust tone

•  Supports Higher Boost Levels for Tuned Cars – Essential for big power builds

•  Maximizes Airflow Efficiency – Designed for street, track & high-performance applications

The OEM downpipe restricts airflow, limiting your BMW’s full performance potential. Upgrading to a high-flow downpipe ensures better turbo efficiency, increased power, and an improved exhaust note, making it a must-have for any tuned N55 build.

 Recommended Supporting Mods for Maximum Performance:

 ECU Tune (MHD or Bootmod3) Required to Maximize Gains

 Aftermarket Intake System for Increased Airflow

 Upgraded Charge Pipes for Better Boost Management

 Front-Mount Intercooler to Reduce Intake Temperatures

 Cat-Back Exhaust for Additional Flow & Aggressive Sound

 Tuning Required to Maximize Performance & Avoid Check Engine Light (CEL).
