Catalytic Converter for Infiniti Q60 (2017-2022) 3.0L

Direct-Fit Stainless Catalytic Converter Pair for 2017-2022 Infiniti Q60 (CV37)

What it Does: This left and right direct-fit catalytic converter set restores emissions scrubbing and factory exhaust flow on the 2017-2022 Infiniti Q60 (CV37) equipped with the VR30DDTT 3.0L twin-turbo V6.

The Stock Infiniti Q60 Converter Failure

On the CV37 chassis, the VR30DDTT 3.0L twin-turbo V6 exposes factory catalytic converters to extreme exhaust gas temperatures and rapid thermal cycling. Sustained heat soak sinters the OEM precious-metal washcoat and degrades oxygen storage capacity, triggering P0420 or P0430 efficiency faults. Simultaneously, vibration and thermal shock fracture the brittle ceramic core, causing internal substrate rattle and elevated exhaust backpressure under boost.

Common Symptoms of a Failing OEM Catalytic Converter

• OBD-II Faults: Persistent P0420 or P0430 codes triggered by low downstream oxygen sensor efficiency.
• Substrate Rattle: Metallic buzzing beneath the floorpan from a fractured ceramic honeycomb core.
• Power Loss: Sluggish turbo spool and failed emissions tests from restricted exhaust flow.

The Direct-Fit Stainless Exhaust Solution

This matched left- and right-bank assembly features stainless steel bodies (8-inch length, 5-inch height) and piping to resist rust and thermal cracking. Inside, a ceramic honeycomb substrate with a precious-metal washcoat converts HC, CO, and NOx gases to restore OBD-II compliance. Factory-style turbo joints, rear 2-bolt flanges, mounting brackets, and oxygen sensor ports enable bolt-on installation without cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the CV37 Q60?

Yes. Fits 2017-2022 Infiniti Q60 VR30DDTT 3.0L models (Pure, Luxe, Sport, Red Sport 400). Excludes 2.0L turbo and 3.7L engines. EPA federal only—not CARB approved or legal in CA, NY, CO, or ME.

Will this clear P0420/P0430 codes, and are O2 sensors included?

Yes, for converter faults; O2 sensors are excluded. Fresh catalysts restore efficiency to clear P0420/P0430 codes; inspect for exhaust leaks and transfer or replace sensors.

Are gaskets and mounting hardware included for installation?

Yes, two ring seals and two 2-bolt flange gaskets are included. Penetrate seized bolts on a cold exhaust, torque evenly, and verify zero leaks.
