Exhaust headers for BMW 3 series E46 M3. These high performance headers were developed in Germany by a leading tuner and are manufactured of out heavy gauge T304 stainless steel for long life. They are intended for track and off road use only unless you weld in catalytic converters.
- Design utilizes a F1-style Merge collector for reduced turbulence and creates more horsepower and torque.
- All T304 stainless steel, TIG welded and polished finish
- Includes 4 O2 (lambda) sensors just like the original down pipe configuration, does not include catalytic converters - not useable on the public roads! Check your local regulations.
- Improvement is approximately 12 hp. With our ECU tuning software upgrades we have seen increases of over 30 HP.
- Design utilizes equal length headers, smooth mandrel bends and large F1-style collectors
- Headers really make the car noticeably faster across the rpm range with minimal additional noise.
- Straight forward installation.
