Wagner Tuning Monolith 200CPSI EU6 Catalyst – Ø150x120mm
The Wagner Tuning Monolith is a high-flow universal catalyst module built for performance exhaust applications. Supplied as a bare monolith ready for welding into a custom housing or downpipe, it gives fabricators and tuners a flexible solution for replacing restrictive OEM catalysts or building a sports cat from scratch.
With a 200 cells per square inch (CPSI) cell density, this catalyst strikes a sensible balance between exhaust gas cleaning and flow. Lower cell counts allow gases to pass through more freely, helping to reduce backpressure and free up power, particularly on turbocharged engines where exhaust flow has a direct impact on response and output.
Key Features
- High-quality EURO 6 compliant coating for effective emissions reduction
- 200 CPSI cell density for improved flow over standard OEM catalysts
- Outer diameter: 150mm, length: 120mm
- Bare monolith design, ready to be welded into a custom housing
- Suitable for petrol applications in motorsport builds
What Does a Sports Catalyst Do?
A catalytic converter (or “cat”) cleans up harmful gases produced by the engine before they leave the exhaust. Factory cats are often very restrictive, which can choke a tuned engine. A sports cat like the Wagner Monolith uses a lower cell density to let gases flow more easily while still treating emissions, helping to recover power lost through restrictive OEM components and reduce exhaust backpressure.
Installation Notes
This is a universal welded-in monolith, not a bolt-on part. It is intended to be installed by an experienced exhaust fabricator into a suitable stainless steel housing. Correct positioning in the exhaust system, along with proper heat management and welding technique, is essential to ensure the catalyst performs as intended and lasts in service.
