Performance and Sound
By installing these catless race headers for the M52TU and M54 engines, you ensure your engine gets better flow due to lower back pressure. The DCE Parts catless race headers have a lightweight header design, which channels the exhaust gases into a 3-to-1 collector .
This ensures optimal flow and a deep, aggressive sound that perfectly underscores the character of the naturally aspirated inline-six. The result is an estimated 15-25 hp gain , improved throttle response, and improved power and torque throughout the rev range.
Material and Construction
The headers are crafted from high-quality stainless steel and expertly TIG-welded for maximum strength and durability. The lightweight design saves weight without sacrificing strength.
The headers retain the original OEM O2 sensor positions for easy installation and compatibility.
Installation and Compatibility
IMPORTANT: For Left Hand Drive (LHD) models only!
NOTE M52TU owners: The headers are NOT a plug-and-play fit for the M52TU midpipe. For M52TUs, you will either need an M54 mid-section or you will need to modify the flanges on the M52TU mid-sections.
These catless race headers are compatible with the following BMW models with M52TU/M54 engines:
- BMW E46 320i, 323i, 325i, 328i, 330i
- BMW Z3 (M52TU/M54)
The headers fit the original OE exhaust (with the above note for M52TU). All necessary mounting hardware is included. Professional installation is recommended.
Optional: For optimal operation and power output, the vehicle may require an ECU remap.
High-Flow Catalytic Converters: The DCE Parts M52TU/M54 headers do not include high-flow catalytic converters. These can be ordered separately. Note: The high-flow catalytic converter must be welded into your midpipe.
