Description
Upgrade from the stock B46 downpipe to the MAD B46 catted downpipe for maximum airflow, power, and sound.
The MAD BMW B46 catted downpipe is the perfect upgrade for getting more performance and a cleaner exhaust tone while keeping your setup street-friendly. The built-in high-flow catalytic converter reduces restriction compared to the factory cat, allowing your turbo to spool quicker and push more power. At the same time, it helps maintain drivability.
On a tuned BMW B46 with the stock turbo, you can expect gains of up to 30 horsepower, with even more on upgraded turbo setups.
The flex section helps reduce stress from engine movement and heat cycles, making it a long-lasting, reliable upgrade.
This downpipe is designed specifically for U.S. B46 models and is not compatible with vehicles equipped with OPF.
