Wagner Tuning 200cpi Catalytic Converter with EU6 Coating

The Wagner Tuning 200cpi Catalytic Converter is a high-flow motorsport cat designed to reduce exhaust backpressure while still cleaning up emissions through its EURO 6 compliant coating. It’s a popular choice for tuners looking to free up power on modified petrol engines without running a fully decatted system.

Compared to a standard OEM catalytic converter, the lower cell density (200 cells per square inch) allows exhaust gases to flow more freely. The result is improved exhaust efficiency, a stronger top-end response and a small but worthwhile gain in power, particularly on turbocharged engines where backpressure has a direct impact on spool and performance.

Key Features

• Universal motorsport catalytic converter with EURO 6 coating
• 200 CPSI cell density for improved exhaust flow
• Helps increase horsepower and reduce exhaust backpressure
• Suitable for engines producing up to 500PS
• Quality stainless steel construction built for motorsport use

What Does CPSI Mean?

CPSI stands for “cells per square inch” and refers to the density of the honeycomb structure inside the catalytic converter. A lower CPSI (such as 200) means fewer, larger cells, which allows exhaust gases to pass through with less restriction. This typically delivers better performance than a standard cat, while the EURO 6 coating still helps reduce harmful emissions.

Why Fit a Sports Cat?

A high-flow sports catalytic converter is a sensible middle ground between a restrictive factory cat and a full decat pipe. You’ll see benefits including:

• Reduced exhaust backpressure for improved turbo response
• Modest power and torque gains, especially when paired with other exhaust upgrades
• Cleaner emissions compared to running no cat at all
• A slightly more aggressive exhaust note

Fitment

This is a universal catalytic converter, designed to be fabricated into custom or aftermarket exhaust systems. It suits a wide range of motorsport applications where the existing cat needs replacing or where a high-flow upgrade is desired. Please refer to the Vehicle Fitment tab or use the site’s vehicle lookup to check suitability, and confirm pipe diameter and overall dimensions before ordering.

Important: This product is intended exclusively for motorsport vehicles used outside of public roads (outside the StVZO). By purchasing this product, you confirm that it will not be fitted to a vehicle driven on public highways.

Maximum rated power: 500PS. Fitting this catalyst to an engine producing more than this may result in damage to the cat and is not recommended.
