Less restriction, more flow, a deeper exhaust note, and the factory O2 sensor location is retained for plug-and-play installation on stock or aftermarket exhausts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eStock 350Z and G35 cats are a major flow restriction, particularly once you've added a Y-pipe and catback. Swapping to high-flow cats with a 300-cell metallic substrate opens up the exhaust path significantly while still providing meaningful catalytic activity. Magnaflow's metallic substrate handles heat cycling better than ceramic alternatives, and the 2.5\" mandrel-bent piping ties cleanly into both OEM and aftermarket exhaust systems built to factory specs.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eNissan 350Z and Infiniti G35 equipped with the VQ35DE engine (Non-HR).\u003c\/strong\u003e Fits both G35 Sedan and G35 Coupe, including G35x AWD sedan per ISR's confirmation. \u003cstrong\u003eWill not fit the 350Z HR or G35 with the VQ35HR engine\u003c\/strong\u003e, which use different cat geometry.
