Catalytic Converter for Infiniti G35 (2007-2008) 3.5L Left & Right

Direct-Fit Catalytic Converter Set for 2007-2008 Infiniti G35

What it Does: The direct-fit left and right catalytic converter set replaces deteriorated factory catalytic converters on the 2007-2008 Infiniti G35 to restore exhaust flow dynamics, clear catalyst efficiency trouble codes, and ensure federal emissions compliance.

The Stock Infiniti G35 Substrate Deterioration and Exhaust Restriction

Factory catalytic converters on the V36 platform endure aggressive thermal cycling and sustained high-RPM exhaust velocity. Over time, the internal ceramic monolith suffers washcoat sintering and cell wall breakdown, leading to fragmented substrate cores. This deterioration causes excessive exhaust backpressure, restricted scavenge velocity, and persistent P0420/P0430 diagnostic trouble codes as catalyst efficiency drops below acceptable ECM thresholds.

The Engineering Solution

Engineered as a pair of precision bolt-on assemblies, this direct-fit system restores critical volumetric efficiency to the VQ35HR exhaust path. Constructed with high-grade stainless steel outer shells and robust, high-surface-area ceramic substrates loaded with washcoat precious metals, these converters facilitate proper chemical conversion without choking high-RPM gas flow. Thick, laser-cut mounting flanges and pre-positioned O2 sensor bungs allow seamless integration with existing factory headers and Y-pipe connections without cutting or custom fabrication.
