Yeoflagtrade 3-Inch High-Flow Catalytic Converter Pair — Stainless Steel, O2 Sensor Port, EPA Compliant

Yeoflagtrade's 3-inch high-flow catalytic converter pair is a stainless-steel, EPA-compliant replacement designed to restore quiet operation and cleaner exhaust flow while accommodating a factory oxygen sensor port.

This set includes two 3" inlet/outlet catalytic converters manufactured from corrosion-resistant stainless steel for durability and sustained performance. Built as universal direct-fit units, they are engineered to meet or surpass original-equipment standards and are factory-tested so you can install them immediately. The converters feature a three-way catalyst core that helps reduce common exhaust emissions and smooth engine tone without extensive modification.

Will these converters fit my vehicle and how do I match them?

These are universal direct-fit catalytic converters with a 3-inch inlet and outlet diameter. Verify the pipe diameter and orientation on your vehicle before ordering to ensure proper fitment. They include a standard O2 sensor port for easy integration with vehicles that use an upstream oxygen sensor.

• Inlet/outlet diameter: 3 inches — confirm your exhaust pipe measures the same.
• Quantity: two pieces — suitable for systems that require a pair.
• O2 sensor port included — compatible with most factory oxygen sensors.
• Universal direct-fit design — may require minor alignment or clamp/weld depending on your exhaust layout.

What materials and construction should I expect from these converters?

Yeoflagtrade builds these converters with stainless-steel housings and a three-way catalytic core to support long service life and reliable performance. The robust shell resists rust and road corrosion, while the internal substrate is formulated for oxygen storage and emission control.

• Stainless-steel outer shell for corrosion resistance and longer life.
• Three-way catalyst core to address hydrocarbons, CO, and NOx.
• Designed for sustained oxygen storage capacity for stable operation.
• Factory-tested construction to match original-equipment expectations.

How straightforward is installation and what tools are needed?

These converters are supplied pre-tested and intended for direct-fit installation, so most experienced DIYers or professional exhaust shops can install them quickly. Depending on your exhaust layout, installation may require clamps, welding, or replacement gaskets to secure a leak-free fit.

• Ready for immediate installation after verification of fitment.
• Common installation methods: bolt-on clamps or welding to exhaust piping.
• May require basic tools: wrenches, pipe cutter, welding equipment if chosen.
• O2 sensor port allows reuse of original sensor—no extra sensor needed in many cases.

Who this product is for: This 3" catalytic converter pair from Yeoflagtrade is aimed at vehicle owners, hobbyist mechanics, and repair shops needing a durable, high-flow replacement that balances performance and emissions compliance. It's a solid choice for drivers replacing damaged or noisy catalytic converters, or restoring exhaust flow on 3-inch systems, provided local regulations permit universal replacements. Note: universal catalytic converters cannot be shipped to California, Colorado, New York, or Maine.
