About Us

Klarius Products Ltd is the largest manufacturer of aftermarket emissions components in the UK, based in Cheadle, Staffordshire. The business offers a range of over 10,000 premium components, available with next morning delivery in vast majority of the UK. Parts offered by Klarius include exhausts, catalytic converters (CATs), diesel particulate filters (DPFs), mountings and accessories – all of which are designed to match or exceed the application performance of the equivalent OE part. Products cater for most of the automotive spectrum, incorporating everything from SUVs to sports cars, classics to light commercial vehicles and everything in-between.


Our focus on quality is absolute, which is why all of our applicable exhausts, CATs and DPFs are type-approved as standard. We employ innovative materials, skilled technicians and state-of-the-art automated production methods to achieve truly market leading emissions products. Our lean philosophy towards manufacturing and supply management ensures we remain competitive while always have the product you require available in stock.

This quality approach starts with our R&D department, which develops new parts and rigorously tests them, including a ‘fit’ test on real world vehicles. An exclusive on-site test track allows independent ratification of noise – part of the Type-approval test that guarantees a Klarius product will perform exactly as it is required to when released to the market.

As a result, we offer a 2 year warranty and a ‘Fit First Time’ guarantee as standard for our entire product range.



We are always keen to meet energetic and talented professionals who would like to join our team.
