Wagner Tuning 300cpi Catalytic Converter with EU6 Coating
The Wagner Tuning 300cpi catalytic converter is a universal motorsport catalyst designed for builders looking to maintain emissions control while reducing exhaust restriction. Featuring a high-quality EURO 6 coating, it offers a strong balance between cleaner exhaust gases and improved flow, making it a sensible choice for performance projects where every bit of efficiency counts.
By using a 300 CPSI (cells per square inch) substrate, the converter creates less back pressure than a standard road-going cat. Lower back pressure means the engine can expel exhaust gases more freely, which typically translates into improved throttle response and a modest gain in horsepower, particularly when paired with other supporting upgrades such as a downpipe or sports exhaust system.
Why Choose This Wagner Tuning Catalyst?
- High-quality EURO 6 coating for effective emissions reduction
- 300 CPSI cell count for reduced exhaust back pressure
- Supports increased horsepower when used with other performance upgrades
- Suitable for engines producing up to 350 PS (approximately 345 bhp)
- Universal design, ideal for custom motorsport exhaust builds
What Does CPSI Mean?
CPSI stands for “cells per square inch” and refers to the density of channels inside the catalyst’s honeycomb core. A lower CPSI count (such as 300) allows exhaust gases to pass through more freely than a standard 400 or 600 CPSI cat, reducing restriction while still providing meaningful emissions treatment thanks to the EURO 6 coating.
Important Usage Information
This catalyst is intended exclusively for motorsport vehicles operated outside of public road regulations (StVZO). By purchasing this product, you confirm that it will not be fitted to a vehicle used on public roads. Please ensure your build complies with the relevant legal requirements in your region before installation.
Fitment
This is a universal motorsport catalyst suitable for custom exhaust fabrication and a wide range of performance applications up to 350 PS. Dimensions on the technical drawing are stated in millimetres. Please refer to the Vehicle Fitment tab or use the site’s vehicle lookup tool to confirm suitability for your specific project, and always check the inlet and outlet dimensions against your existing exhaust system before purchase.
