 Why Upgrade to a Performance Downpipe?

•  Faster Turbo Spool & Improved Throttle Response

•  Increased Horsepower & Torque Gains

•  Louder, More Aggressive Exhaust Note

•  Supports Higher Boost Levels for Tuned Cars

•  Improves Turbo Efficiency & Reduces Exhaust Backpressure

The factory downpipe restricts airflow, limiting power potential and throttle response. Upgrading to a high-flow downpipe ensures better exhaust flow, more power, and a deeper exhaust tone, making it a must-have for tuned B46/B48 engines.

 Recommended Supporting Mods for Maximum Performance:

 ECU Tune (MHD or Bootmod3) to Maximize Gains

 Upgraded Intake for Increased Airflow

 Intercooler Upgrade to Reduce Intake Temps

 Aftermarket Exhaust for Enhanced Sound & Flow

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