Lexus GS350 Catalytic Converters
Lexus GS350 catalytic converters reduce pollutants in V6 exhaust. A-Premium offers individual side-specific assemblies, paired replacements and universal rear bodies for failed catalysts.
Rear-wheel-drive and all-wheel-drive GS350s have separate right-side replacement options. The rear-wheel-drive front pair is therefore not an all-drivetrain package. Once the drivetrain and failed section are identified, an individual replacement can address one side or a paired set can cover a repair involving both front units.
Why Choose Lexus GS350 Catalytic Converters from A-Premium?
A-Premium's GS350 selection includes these material and package benefits.
- Ceramic catalyst cores: The side-specific A-Premium assemblies use ceramic substrates. The internal coated surfaces treat exhaust gases flowing through the replacement.
- Stainless steel rear bodies: Walker universal rear options use stainless steel housings. Corrosion resistance helps protect the converter enclosure from moisture beneath the car.
- Gaskets and bolts supplied: The rear-wheel-drive A-Premium front pair includes gaskets and bolts. Fresh joint parts help reseal and fasten both replacements when the old assemblies are removed.
FAQs About Lexus GS350 Catalytic Converters
Does the AP Emissions GS350 front-right assembly include all mounting hardware?
No. It supplies inlet and outlet gaskets and outlet hardware, but not inlet hardware. Separate inlet fasteners may be needed when the originals are corroded or damaged. This package differs from a kit that supplies bolts for both connections.
Does a GS350 universal rear converter require pipework?
Yes. The Walker rear bodies use pipe connections and require fitting into the exhaust. They do not supply a complete shaped rear section. The remaining pipe must be sound enough for secure joints, or additional tubing needs replacement.
What affects Lexus GS350 catalytic converter replacement cost?
Drivetrain, failed position and the number of units being repaired affect the parts needed. Access, seized fasteners and universal-body fabrication affect labor. Compare estimates for the same components and include any contributing engine repair.
Can the oxygen sensors be reused with a new converter?
Serviceable sensors can be reused when their threads and wiring remain intact. A sensor that is faulty or damaged during removal needs separate replacement. The presence of a mounting port helps installation but does not establish that the existing sensor is healthy.
