ISR Performance High Flow Cat - Infiniti Q60 3.0T

The ISR Performance High Flow Cats are a direct-fit catalytic converter upgrade for the 2017 and newer Infiniti Q60 3.0T. They reduce restriction over the factory cats, retain the factory oxygen sensor locations, and add a more aggressive exhaust tone without going fully catless.

What It Does

The VR30DDTT in the Q60 3.0T has restrictive factory catalytic converters that hold back exhaust flow and limit the gains from a downpipe-back exhaust upgrade. These ISR High Flow Cats use a 300 cell spun metallic substrate that flows significantly better than the OEM units while still converting harmful exhaust gases. The result is improved exhaust scavenging, a noticeable bump in power, and a deeper, more aggressive tone, all without removing emissions equipment entirely.

Construction

Fully TIG welded with true mandrel bends throughout. The metallic substrate is more durable than ceramic alternatives and handles the higher exhaust gas temperatures common on twin-turbo applications. Stainless steel construction for long-term corrosion resistance.

Fitment

• 2017+ Infiniti Q60 3.0T (CV37, VR30DDTT engine)

Bolts up to the factory exhaust or to aftermarket exhausts built to OEM specs. Retains the factory oxygen sensor locations, so no tune is required to address O2 sensor positioning.

What's in the Box

• 2x Stainless steel high flow catalytic converters
• 3x 2-bolt exhaust gaskets
• 1x 3-bolt exhaust gasket
• 9x bolts
• 9x nuts
