1. 최고의 기능 정비사 신뢰
고효율 변환
동시에 산화시킨다 $\text{CO}\rightarrow\text{CO}_2$, 감소시킨다 $\text{NO}_x\rightarrow\text{N}_2$, 그리고 화상 $\text{HC}\rightarrow\text{H}_2\text{O}$ ~에 $\lambda\approx1$—fully meets and exceeds Euro 4, Euro 5, and OBDII standards.
Low-Backpressure Oval Design
The high-performance 400 CPSI cell density combined with an optimized oval/flat spun body shape reduces exhaust restriction, maximizing flow capacity compared to generic restrictive units.
내구성 우선
Built with a high-grade 409L stainless steel body and an integrated aluminized steel heat shield to withstand extreme continuous exhaust heat, protect underbody components, and prevent thermal cracking.
타협 없는 핏
Features a pre-welded O2 sensor port for hassle-free oxygen sensor re-installation, specifically tailored for front position applications to ensure a reliable retrofit and upgrade.

3. 이것이 실제 문제를 해결하는 이유
1. 2.5″ Universal Catalytic Converter Resolves Emission Test Failures
Restores factory-level $\text{CO}/\text{HC}/\text{NO}_x$ conversion, helping gasoline vehicles easily pass mandatory local smog checks and strict OBDII environmental compliance tests.
2. 노후된 배기 시스템
Prevents recurring check engine lights and P0420 codes caused by degraded or melted substrates, providing a durable structural replacement that extends exhaust system lifespan.
3. 성능 저하
The optimized 400 CPSI high-flow design eliminates internal exhaust blockages, reducing backpressure so the engine breathes smoothly, recovering original horsepower and fuel efficiency.
4. 비용이 많이 드는 수리
Equipped with a pre-welded O2 sensor port and precision-engineered 2.5-inch inlets/outlets, minimizing alignment adjustments during installation and saving valuable shop labor costs.
4. 업계 전문가의 추천
“This unit’s 400 CPSI high-performance substrate balances flow velocity and surface catalytic area perfectly. For workshops dealing with Euro V compliance issues, it’s a highly reliable aftermarket solution.”
– 마이크 R., Master Technician (ASE Certified)
“The high-grade 409L stainless steel casing and integrated aluminized shielding handle thermal stress exceptionally well. No lambda sensor errors post-installation, which shows excellent calibration.”
