ISR Performance High Flow Catalytic Converters - Infiniti Q60 3.0T

ISR Performance high flow catalytic converters for the Infiniti Q60 3.0T free up the twin turbo VR30DDTT without running catless. Each unit is custom made with a 300 cell spun metallic substrate, which is considerably less restrictive than the dense factory bricks while still converting exhaust gases. The pair bolts in where the stock cats sit and sharpens the exhaust note in the process.

Construction

• 300 cell spun metallic substrate
• Stainless steel housings and piping
• Fully TIG welded with true mandrel bends throughout
• Factory oxygen sensor locations retained, so sensors plug in as before
• Adds a more aggressive exhaust tone

Fitment and compatibility

Infiniti Q60 3.0T. The ISR HFCs bolt up to the factory exhaust or to an aftermarket exhaust, provided the aftermarket system was built to OEM flange specs.

In the box

• 2x stainless steel high flow cats
• 3x two bolt exhaust gaskets
• 1x three bolt exhaust gasket
• 9x bolts and 9x nuts

Things to know

On turbocharged engines, reducing restriction after the turbine helps the turbos spool and lowers back pressure, which is where most of the gain from a high flow cat comes from. A lower cell count can affect readiness monitors on some vehicles; a tune is a common companion to this part.
