Description
The Active Autowerke N26 Catted Downpipe is the ultimate performance upgrade for your BMW F-Chassis 228i, 328i, or 428i equipped with the N26 engine. By replacing the restrictive OEM downpipe, this high-flow GESI catted downpipe helps unlock significant power gains and quicker turbo spool. Specifically designed for the N26 engine, this downpipe is not compatible with the N20 engine—ensure you verify your vehicle’s engine type using your VIN before purchasing.
This downpipe features a 4-inch GESI High Output Catalytic Converter, which is EPA-compliant in 49 states and helps reduce emissions while eliminating the Check Engine Light (CEL). Crafted from 3.5-inch diameter 304 stainless steel, it ensures durability, maximum power output, and optimal flow, resulting in noticeable horsepower and torque improvements.
The GESi HO-Series Catalytic Converters are rated for engines producing between 500 and 850 horsepower, and they are designed to maintain a high-flow capacity while significantly reducing back-pressure. This ensures improved turbo efficiency and more horsepower without compromising emissions compliance.
