Upgrade from the stock B46 downpipe to the MAD B46 catless downpipe for maximum airflow, power, and sound

The MAD BMW B46 catless downpipe is the perfect upgrade for unlocking the full potential of your turbocharged engine. By removing the restrictive factory catalytic converter, this downpipe allows your turbo to spool faster and more efficiently, giving you better throttle response and more power across the rev range. You’ll also notice a deeper, more aggressive exhaust tone.

On a tuned BMW B46 with the stock turbo, you can expect gains of up to 30 horsepower, with even more potential on upgraded turbo setups.

The built-in flex section helps reduce stress on the system by absorbing vibration and movement from the engine and heat cycles, making it a reliable and long-term upgrade.

This downpipe is designed specifically for U.S. B46 models and is not compatible with vehicles equipped with OPF.


Features

  • Compatible with both right-hand drive and left-hand drive vehicles

  • Smooth mandrel bends for maximum flow and zero drone

  • Up to 30HP gain on stock turbos, more with upgraded setups

  • Flex section for added durability and vibration absorption

  • Precision fitment for an easy install
