Wagner Tuning 200cpi Catalytic Converter with EU6 Coating

Description

Wagner Tuning 200CPSI Catalytic Converter with EU6 Coating

The Wagner Tuning 200CPSI Catalytic Converter is a high-flow motorsport cat designed to reduce exhaust backpressure while still providing meaningful emissions control through its EURO 6 coating. It is a popular choice for tuners building custom exhaust systems who want to free up power without running a fully decatted setup.

Compared to a standard OEM catalytic converter (typically 400 or 600 CPSI), the lower 200 CPSI cell density allows exhaust gases to flow through more freely. The result is improved exhaust efficiency, reduced backpressure and better turbo response on forced induction engines, while the EU6 coating helps manage harmful emissions far better than a straight-through decat pipe.

Key Benefits

• Universal fitment for custom motorsport exhaust builds
• 200 CPSI cell density for improved flow over OEM units
• EURO 6 coating helps reduce emissions
• Frees up power and improves throttle response, particularly on turbocharged engines
• Suitable for engines producing up to 380PS

What is CPSI?

CPSI stands for “cells per square inch” and refers to the density of the honeycomb structure inside the catalyst. A lower CPSI count means larger, fewer cells, which allows exhaust gases to pass through with less restriction. The trade off is slightly less surface area for the catalyst coating to react with the gases, though the EU6 coating used here is highly efficient.

Construction and Specification

The catalyst body is built from stainless steel for durability and corrosion resistance under sustained high temperatures. Its universal design allows it to be welded into a variety of custom or modified exhaust systems, making it ideal for fabricators and workshops.

Important Usage Notice

This product is intended exclusively for motorsport use on vehicles not driven on public roads. It is not road legal under StVZO (German road traffic regulations) or equivalent road use legislation in other countries. By purchasing this product, you confirm it will only be fitted to vehicles used in motorsport or off-road environments.

Maximum rated power output: 380PS. Fitting this catalyst to engines producing more than this may result in premature failure of the catalyst substrate.

Fitment

This is a universal motorsport catalyst suitable for a wide range of custom exhaust builds. Please refer to the Vehicle Fitment tab or use the site’s vehicle lookup tool to confirm suitability, and check the dimensions to ensure compatibility with your existing or planned exhaust system.
