HKS Metal Catalyzer for Subaru Legacy B4 (2003-2006)
Upgrade your Subaru Legacy B4 with the HKS Metal Catalyzer, a high-performance component designed specifically for the 2003-2006 models equipped with the EJ20X engine. HKS, a leader in aftermarket auto parts since 1973, has engineered this catalyzer to enhance both output and purification, ensuring your vehicle runs efficiently while meeting emissions standards.
Key Features
- Advanced Design: This Metal Catalyzer features a combined unit type of Front Pipe with a 150-cell catalyzer, optimizing exhaust flow and performance.
- Compatibility: Suitable for both 5MT and 4AT transmissions, certified by public organizations for the 10-15 mode exhaust gas test.
- Improved Efficiency: The redesigned spherical surface gasket and increased pipe diameter at the muffler connection reduce exhaust gas turbulence, enhancing overall intake efficiency.
- Performance Boost: Prevents knocking during EJ20 tuning while lowering secondary exhaust pressure after the turbine and primary exhaust pressure before the turbine.
Fitment
- Subaru Legacy B4 TA-BL5 EJ20X (2003-2006)
Important Notes
- Installation may alter boost pressure characteristics. While compatible with HKS mufflers, using this product with other manufacturers or altered boost settings may require adjustments and inspections for knocking and maximum boost settings.
