Wagner Tuning Monolith 300CPSI EU6 Catalyst – Ø130x85mm
The Wagner Tuning Monolith 300CPSI EU6 is a universal high-flow catalyst module built for performance exhaust applications. With a 130mm outer diameter and 85mm length, it’s designed to be welded into a custom or modified exhaust system, offering a strong balance between emissions control and improved gas flow.
At 300 cells per square inch (CPSI), this catalyst features a less restrictive cell structure than most factory units, which typically run at 400 or 600 CPSI. The result is reduced exhaust backpressure, allowing the engine to breathe more freely and supporting genuine power and throttle response gains, particularly on tuned or turbocharged setups.
What CPSI Means
CPSI (cells per square inch) refers to the density of the honeycomb structure inside the catalyst. A lower CPSI count means larger, more open passages for exhaust gases, which reduces flow restriction. The 300CPSI specification is a popular choice for performance builds where some emissions reduction is still required, but flow is the priority.
Key Features
- High-quality EURO 6 compliant coating
- 300CPSI cell density for improved exhaust flow
- Outer diameter: 130mm, length: 85mm
- Universal weld-in design for custom exhaust fabrication
- Helps reduce exhaust backpressure and support power gains
- Suitable for petrol motorsport applications
Installation
This is a weld-in component intended for installation by an experienced exhaust fabricator. Correct positioning, alignment, and heat management are essential to ensure long catalyst life and proper function. Always make sure the catalyst is fitted in the correct flow direction as indicated by the manufacturer.

MADE TO ORDER in blue means we've partnered with a supplier which primarily makes their products to order. It's not on our shelf, but your order goes into production immediately.
0 IN STOCK in orange means everybody we work with is unfortunately out of stock. Stock is not available in the UK. The best course of action is to place an order to create an allocation from the next batch arriving.
OUT OF STOCK in red. This product is unavailable to order, for whatever reason we're unable to obtain stock or there is an issue with supply/lead times.
We're tuners too!
Our staff are car enthusiasts, we understand the need for speed... This includes getting your orders out the door as quickly and securely as possible!
In some instances, extended lead times are unavoidable. This is as labour-intensive and frustrating for us as it is for you, please know we are doing our best to facilitate your modification goals. Abuse of our staff or systems will not be tolerated.
Thank you, Team PP
In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
