Product Details

The MagnaFlow 5551333 is a California Grade CARB Compliant Direct-Fit Manifold Catalytic Converter engineered to restore proper emissions performance and keep your check engine light off. Designed as a true bolt-on replacement, this converter requires no cutting or welding, making it a straightforward DIY-friendly installation with the proper hand tools.

Key Features:

  • CARB Compliant: Meets or exceeds California Air Resources Board (CARB) requirements, making it legal for use in California and all other CARB-restricted states for listed vehicles
  • Direct-Fit OE Replacement: Replicates the original equipment spun body design for a precise, accurate fit without modification
  • Free-Flowing Mandrel-Bent Tubing: Maintains consistent interior diameter throughout bends for optimized exhaust flow and performance
  • Stainless Steel Construction: Highly corrosion-resistant stainless steel body ensures long-term durability and resistance to heat and road elements
  • Single Laser Fusion Weld: The OE-style spun body design combined with a single laser fusion weld greatly reduces the risk of exhaust leaks
  • Compact, Low-Mass Design: Allows for greater thermal efficiency and faster catalyst light-off
  • 3D Scan-Verified Fitment: MagnaFlow's metrology department uses advanced 3D scanning technology during R&D to ensure the part fits and functions like the original equipment
  • Gaskets & Hardware Included: All necessary installation hardware is included, eliminating the need to reuse potentially corroded factory fasteners and reducing the chance of a leaking seal
  • OEM Cross-Reference: Interchanges with OE part numbers 18190-RGL-A00 and 18190-RN0-A01, among others

This manifold catalytic converter has undergone rigorous additional testing to comply with CARB guidelines, giving you confidence that it meets the strictest emissions standards. Whether you're restoring your vehicle to emissions compliance or simply replacing a worn-out converter, the MagnaFlow 5551333 delivers OE-quality fit, finish, and performance.

The guy i talked to trying to cancel my order he was insiting that I couldn't cancel he was saying that its been shipped but online it was saying it was still there waiting for USPS and it was hard to hear him the back ground was nothing but wind and a lot of noise but other than that it was very satisfying thank you have a blessed day

quick and easy... I needed braided brake lines and once I googled the subject 'your site came up' and next thing I knew I had ordered confirmed...

I never received order confirmation by email. Call 2 days later to make sure order went through. A courteous Customer Service rep told me that order has arrived and package was in shipping. They would send tracking number when one is assigned. Never received one. Pleasantly surprised though when package arrived in 3 days in good order.

Order was delivered fast

Bought this for my 08 yukon. Worked perfect to fix issue. Just a note...this is for the 25896408 gm stamped number. You can not use dorman 590-203, will not work in this year. Unfortunately you must use 590-224 for 08 yukon. This is the cheapest by far after hours of research, both google and dorman websites.

Great prices

Fast checkout.
