DCE Parts - Catless Race Headers for BMW M52TU M54 320i 323i 325i 328i 330i E46 Z3

Through the placement of the catless race headers for the M52 TU and M54 engines, you will ensure that your engine gets a better flow due to a lower back-pressure. The DCE Parts Catless Race Header is a lightweight header design, channeling the exhaust gasses into a 3-to-1 collector design.

The headers do not fit on to the M52TU Midpipe plug and play. For M52TU, you will either need a M54 mid-section or you will need to modify the flanges of the M52TU mid-sections.

Benefits:

• Better throttle response
• Reduction in backpressure
• Beautiful exhaust note
• Estimated 15-25HP+ Gains
• Improved Power and Torque throughout the power band
• Fits on OE exhaust
• TIG welded
• Retains OEM O2 Sensors.

Optionally, for proper operation and optimal power output, the vehicle will need remapping of the ECU. This product is not suitable for road use.

Options

The DCE Parts M52TU M54 Headers do not include High Flow Catalytic Converters. These can be optionally ordered with your headers. Please note that the High Flow Catalytic Converter needs to be welded in your mid-pipe.

Note:

The Catless Headers are only suitable for off-road use. We recommend to check your local law before purchasing the headers.
