2023+ Nissan Z primary cat delete pipes

These bolt directly to the turbos using the factory hardware and replace the primary catalytic converters for optimal flow and more power.

They feature:

• 2.5 inch diameter stainless tube 
• 10mm thick stainless flanges
• 2.5 inch V band flanges to match the factory turbo outlets
• Tig welded

These are a great upgrade when making more power when combined with our secondary high flow cats and cat back system for the Nissan Z. Aka 400Z.
