Sports Catalytic Converters, de-cat and sports cats  – Paramount Performance list a large range of catalytic converters. Some are TUV / EC approved. However, others such as the IPE and Armytrix systems are manufactured outside of Europe and so may not be EC approved. For this reason, some sports catalytic converters and all “De-cat pipes” for sale on the Paramount site are sold for motorsport and off-road use in the UK and EU, and not for road use. Our expert team is on hand if you need any help choosing the right catalytic converters for your use.
