FOMIUZY Nissan Altima Front Catalytic Converter Kit 2007–2013 2.5L L4 — High-Flow EPA‑Compliant Direct-Fit

FOMIUZY High Flow Front Catalytic Converter Kit is a direct-fit replacement engineered to restore emissions control and exhaust flow for Nissan Altima 2.5L L4 models (2007–2013) with the L32 chassis.

This replacement catalytic converter kit is built as a bolt-on direct replacement for many Nissan Altima 2.5L sedans and coupes, designed to meet or exceed OEM fitment and EPA-compliant performance outside of certain high-emission states. Constructed with aluminized stainless piping and a double-layer ceramic carrier, it aims to recover exhaust efficiency, lower noise, and support correct OBD-II operation after factory-cat failure or theft. Verify the part number and chassis fit before ordering, and note installation is improved by bolting first and then welding for a more secure seal.

Which Nissan Altima models does this catalytic converter fit?

This kit is manufactured specifically for the L32 chassis and covers most 2.5L L4 Altima sedans and coupes across the listed years. Always confirm compatibility with your vehicle’s model year and part number before purchase to avoid returns.

• Fits 2007–2012 Nissan Altima 2.5L L4 sedan (4-door).
• Fits 2008–2013 Nissan Altima 2.5L L4 coupe (2-door).
• 2013 sedan owners should check model 16694 to ensure correct fitment.
• Compare your current OEM part number to guarantee match.

How does this kit affect emissions and engine codes?

Replacing a damaged or missing front catalytic converter helps correct elevated emissions and can clear fault codes tied to converter efficiency (for example, P0420). This FOMIUZY unit is produced under strict procedures to conform with federal EPA standards where applicable.

• Designed to restore catalytic conversion efficiency and reduce harmful exhaust byproducts.
• Aids in resolving OBD-II diagnostic trouble codes related to catalyst performance.
• Meets EPA compliance for eligible states; not sold for certain high-emission states at this time.
• Factory-tested to match OEM specifications for reliable operation.

What materials and construction features improve performance and durability?

The converter uses aluminized stainless steel piping and a ceramic carrier built for high temperatures to resist corrosion and maintain oxygen storage capacity. The dual-layer ceramic increases flow area and surface exposure to help balance emissions control and exhaust throughput.

• Aluminized stainless steel body for corrosion resistance and longevity.
• Double-layer, high-temperature ceramic carrier to optimize flow and surface area.
• Factory testing for dimensional and performance consistency with OEM parts.
• Recommended bolt-then-weld installation for improved sealing.

What comes in the box and what warranty support is offered?

The package includes one complete catalytic converter kit ready for installation. FOMIUZY backs the product with a lifetime warranty and customer support to address defects or fitment concerns, aiming to simplify replacement without dealer pricing.

• Includes one catalytic converter kit per order.
• Lifetime warranty coverage for manufacturing defects and failures.
• Customer service available to assist with fitment questions and after-sales issues.
• Save on parts cost compared with many dealer replacement options.

Who is this for? If you drive a compatible Nissan Altima 2.5L L4 and need a direct replacement for a failed, damaged, or stolen front catalytic converter—especially when clearing emissions-related codes or restoring quieter exhaust operation—this FOMIUZY kit is intended for DIY mechanics and professional installers who want OEM-style fitment with improved sealing when welded after bolting. Double-check your vehicle year, chassis (L32), and existing part number before purchase to ensure a correct match.
