100 Cell Catalytic Converters

High Performance 100 Cell Catalytic Converters for Maximum Exhaust Flow

100 cell catalytic converters are designed for maximum exhaust flow and high-performance applications, making them a popular upgrade for modified and turbocharged vehicles. Compared to standard catalytic converters that typically use 400 or 200 cells, a 100 cell high-flow catalytic converter significantly reduces exhaust restriction, allowing gases to exit the engine more efficiently and helping improve horsepower, throttle response, and turbo spool.

At Exhaust Shop Australia, we offer a range of high-performance 100 cell catalytic converters built from durable stainless steel and engineered for motorsport and high-output street vehicles. These performance catalytic converters are ideal for enthusiasts upgrading their exhaust systems, installing turbo upgrades, or building custom performance exhaust setups.

Our 100 cell cats are commonly used in custom exhaust fabrication, race builds, turbo upgrades, and performance exhaust systems, providing the best balance of flow and emissions control where maximum performance is the goal.

Upgrading to a 100 cell catalytic converter is one of the most effective ways to improve exhaust system performance on modified vehicles. The reduced cell density inside the converter allows exhaust gases to pass through more freely, reducing backpressure and helping engines produce more power.

These high-flow catalytic converters are commonly used in turbocharged engines, performance builds, and track vehicles where exhaust efficiency is critical. They are often paired with performance headers, turbo back exhaust systems, high-flow mufflers, and stainless steel exhaust piping to create a complete high-performance exhaust setup.

When choosing a catalytic converter, it's important to consider pipe diameter, inlet and outlet configuration, and compatibility with your exhaust system. Many performance builds use 100 cell cats in custom exhaust systems, motorsport applications, and high horsepower street cars where improved exhaust flow is essential.

At Exhaust Shop Australia, we stock a wide range of high flow catalytic converters, exhaust components, and performance exhaust upgrades, helping enthusiasts and workshops build efficient and powerful exhaust systems.

Frequently Asked Questions

What is a 100 cell catalytic converter?

A 100 cell catalytic converter is a high-flow catalytic converter that contains around 100 cells per square inch in its internal honeycomb structure. This lower cell density allows exhaust gases to pass through more freely, improving exhaust flow and engine performance.

Do 100 cell catalytic converters increase performance?

Yes. Because they create less exhaust restriction than standard catalytic converters, 100 cell catalytic converters can help improve horsepower, throttle response, and turbo spool in high-performance vehicles.

Are 100 cell catalytic converters good for turbo cars?

Yes. 100 cell catalytic converters are commonly used in turbocharged vehicles because they reduce backpressure and help turbochargers spool faster, improving overall engine efficiency.

Are 100 cell catalytic converters street legal?

In many cases, 100 cell catalytic converters are designed primarily for motorsport or off-road use. Regulations vary by region, so it's important to check local emissions laws before installing one on a street-driven vehicle.
