MagnaFlow 49629 Direct-Fit Catalytic Converter for 07-21 Tundra 5.7L Driver Side

Vehicle Fitment

• 2007-2021 Toyota Tundra (5.7L V8, RWD/4WD, 126" Wheelbase Only, Driver Side)
• 2018-2019 Toyota Tundra (5.7L V8 Flex Fuel, 126" Wheelbase Only, Driver Side)

Fitment Notes

• Fits Toyota Tundra with 126-inch wheelbase only. Not confirmed for 139.8-inch or 145.7-inch wheelbase configurations.
• This is a Federal/EPA-compliant converter only. Not legal for sale, installation, or use in California, Colorado, or New York.
• Position: Driver Side (Left Bank). This converter does not replace the passenger-side unit; see MagnaFlow 49630 for the passenger-side application.
• Toyota Sequoia 5.7L fitment is referenced by some distributors but cannot be confirmed from two independent sources for specific model years; Sequoia owners should verify against MagnaFlow's official fitment guide before purchasing.
• Does not fit 2022 or newer Toyota Tundra (platform change to twin-turbo V6).
• 2018-2019 Flex Fuel 5.7L Tundra fitment confirmed.

Features

• OEM Grade direct-fit design engineered to replace the factory driver-side catalytic converter with no cutting, welding, or fabrication required.
• Constructed from high-strength 16-gauge 409 stainless steel tubing for exceptional corrosion resistance and long-term durability in high-heat underbody environments.
• Spun-body design replicates the OE construction with a single laser fusion weld for superior leak resistance and structural integrity.
• Free-flowing mandrel-bent tubing maintains factory exhaust flow dynamics for optimal performance and fuel efficiency.
• Features pre-cat and post-cat O2 sensor ports positioned to OEM specifications, preventing check engine light codes from O2 sensor signal errors.
• OE-sized barbed exhaust hangers made from corrosion-resistant 410 stainless steel reduce noise, vibration, and harshness (NVH) during operation.
• Developed using MagnaFlow's 3D laser scanning metrology system to ensure precise OEM-like fitment on the 2007-2021 Tundra platform.
• Built to OEM Grade standards with higher precious metal catalyst loading than standard-grade converters for superior emissions reduction efficiency.
• Meets and exceeds Federal EPA emissions requirements for OBDII-equipped vehicles registered outside CARB-regulated states.

Product Description

The MagnaFlow 49629 is a Federal/EPA-compliant, OEM Grade direct-fit catalytic converter designed specifically for the 2007-2021 Toyota Tundra equipped with the 5.7L V8 engine, including Flex Fuel variants from 2018-2019. This driver-side (left bank) converter replaces OE Toyota part numbers 17450-0S010, 17450-0S011, 17450-0S140, 17450-0S170, 17450-0S200, 17450-0S220, and others, making it a precise, bolt-on emissions replacement that restores factory performance without any cutting, bending, or welding. Important fitment note: this converter is designed for the 126-inch wheelbase Tundra configuration only and is not compatible with larger cab/bed combinations on different wheelbases.

MagnaFlow engineered the 49629 to exceed OEM Grade standards by applying a higher loading of precious metal catalyst to the ceramic substrate than standard-grade converters, resulting in improved catalytic efficiency and more reliable OBDII monitor function. The spun-body design with a single laser fusion weld replicates the OE construction profile for a tight, leak-free installation. The pre-cat and post-cat O2 sensor ports are positioned to factory specifications to prevent false O2 sensor codes after installation. All included hardware - one Torca clamp and two flat ring gaskets - covers everything needed for a complete bolt-on replacement.

This is a Federal/EPA-compliant converter only and is not legal for sale, installation, or use in California, Colorado, or New York. Tundra owners in those states should reference MagnaFlow's CARB-certified catalog for the appropriate converter. For owners of 2007-2021 Tundras registered in the remaining 47 states and Canada, the 49629 is a professional-grade, warranty-backed emissions solution built to restore performance, eliminate check engine light codes related to catalytic converter failure, and deliver the long-term durability expected from MagnaFlow's OEM Grade line.
