TMR Performance 2023+ Nissan Z VR30DDTT High-Flow Catalytic Converters with Gaskets

Upgrade the exhaust flow and performance of your VR30DDTT-powered vehicle with the TMR Performance Stainless Steel High-Flow Catalytic Converters, designed for the 2023+ Nissan Z and selected Infiniti Q50 models.

The factory catalytic converters are one of the most restrictive sections of the standard exhaust system. These high-flow catalytic converters reduce exhaust restriction, improve gas flow and support increased power and responsiveness while retaining catalytic converter cores for a more street-focused alternative to catless test pipes.

Handmade from premium 304-grade stainless steel, each converter features heavy-duty 10mm flanges, high-flow metallic catalytic cores, factory-style oxygen sensor ports and integrated brace mounting points for secure installation.

• Sharper throttle response
  
• Improved turbocharger response
  
• Increased power potential
  
• More aggressive exhaust sound
  
• Better performance with ECU tuning and supporting modifications

For maximum performance benefits, professional ECU tuning is recommended.

Each TMR Performance high-flow catalytic converter is handmade using high-quality components for strength, durability and consistent fitment.

Construction features include:

• 304-grade stainless steel body
  
• 10mm-thick stainless steel flanges
  
• High-flow metallic catalytic converter cores
  
• Pre-installed oxygen sensor ports
  
• Integrated factory-style brace mounts
  
• Precision-welded construction

What's Included

1 × Pair of TMR Performance High-Flow Catalytic Converters

Includes:

• Left high-flow catalytic converter
  
• Right high-flow catalytic converter

• Installation gaskets

Installation

Direct replacement for the factory catalytic converter section.

Professional installation is strongly recommended.

Due to the location of the factory catalytic converters on the VR30DDTT engine, installation may require specialist tools and additional labour compared with a standard cat-back exhaust installation.

Installation services are available through Sequential Racing in Altona North, Melbourne.

Important Notes

High-flow catalytic converters may increase exhaust volume and alter the vehicle’s exhaust tone.

An engine warning light may occur on some vehicles depending on the catalytic converter monitoring system, vehicle software and current modifications. ECU tuning or additional calibration may be required.

These catalytic converters are designed for performance applications. Compliance with emissions, roadworthiness and noise regulations can vary between states and territories. Buyers are responsible for confirming suitability for road use in their location.
