 Why Upgrade to Catless Downpipes?

•  More Horsepower & Torque Gains – Frees up exhaust flow for higher peak power

•  Reduces Turbo Lag – Allows faster spool times and quicker throttle response

•  Optimized for High-Boost & Tuned N54s – Handles higher power levels without restriction

•  Enhances Exhaust Sound – Adds an aggressive tone while reducing backpressure

•  Built for Long-Term Durability – Constructed from high-quality stainless steel

The factory downpipes on the N54 are restrictive, limiting airflow and turbo efficiency, especially at higher boost levels. Upgrading to high-flow downpipes ensures your turbos operate efficiently, making more power while maintaining reliability.

 Recommended Supporting Mods for Maximum Performance:

 ECU Tune (MHD, Bootmod3) for Optimized Airflow & Fueling (Required for catless downpipes)

 Upgraded Charge Pipes for Improved Boost Delivery

 Front-Mount Intercooler (FMIC) to Reduce Intake Temps

 Aftermarket Exhaust for Maximum Flow & Sound Enhancements

 A tune is required to avoid a check engine light and maximize performance gains.
