Nissan Micra K11 Mani-Cat Delete - Coilpack Engines

The GizFab K11 Mani-Cat Delete is designed to replace the factory manifold-mounted catalytic converter fitted to compatible Coilpack Nissan Micra K11 engines.

It replaces the OEM mani-cat section while retaining the original manifold arrangement, making it suitable for motorsport, off-road and testing applications where the factory primary catalyst is no longer required.

Key Features

• Designed for Nissan Micra K11 Coilpack Engines
• Replaces the Factory Manifold-Mounted Catalytic Converter
• Direct Replacement for the OEM Mani-Cat Section
• Lower Donut Gasket Included
• Fitting Hardware Included
• Re-Uses Factory Upper Mesh Gasket & Crush Seal
• 12-Month Warranty

⚠️ COILPACK ENGINES ONLY

THIS VERSION IS DESIGNED FOR K11 MICRAS WITH THE COILPACK ENGINE CONFIGURATION.

It is not suitable for earlier Distributor / Dizzy engine configurations.

If your vehicle has been engine-swapped or modified during its lifetime, identify the components physically fitted to the vehicle rather than relying solely on registration year.

Replaces the Factory Mani-Cat

On compatible Coilpack K11 models, the primary catalytic converter forms part of the exhaust manifold assembly.

The Mani-Cat Delete replaces this original catalytic converter section while allowing the factory manifold arrangement to be retained.

This makes it a useful option where the factory manifold is being retained but the original manifold-mounted catalyst needs to be removed for a motorsport, competition or testing application.

Removing the catalyst reduces exhaust restriction through this section, although no specific horsepower increase is guaranteed. The actual effect will depend on the engine specification and complete exhaust system.

What's Included?

Each Mani-Cat Delete is supplied with:

• 1x K11 Coilpack Mani-Cat Delete
• 1x Lower Donut Gasket
• Required Fitting Hardware

⚠️ UPPER GASKETS ARE NOT INCLUDED

The Mani-Cat Delete is designed to re-use the factory upper mesh gasket and crush seal.

THE FACTORY UPPER MESH GASKET AND CRUSH SEAL ARE NOT INCLUDED WITH THIS PRODUCT.

The condition of the existing seals should be carefully inspected during installation.

If either seal is damaged, excessively worn or unsuitable for reuse, it should be replaced before installation.

Do not attempt to compensate for damaged or incorrectly seated exhaust seals by excessively tightening the mounting hardware.

Professional Installation Recommended

This product should be installed by a suitably qualified professional.

Before installation, inspect the factory exhaust manifold, mating surfaces, studs, threads and surrounding exhaust components for damage or excessive corrosion.

Following installation, the exhaust system should be checked for:

• Exhaust Leaks
• Correct Alignment
• Adequate Clearance
• Secure Mounting
• Correctly Seated Gaskets & Seals

Installation may:

• Cause the Vehicle to Fail an Emissions Test
• Cause the Vehicle to Fail an MOT or Equivalent Inspection
• Increase Exhaust Emissions
• Increase Exhaust Noise
