Universal Catalytic Converters
Discount Converter, Ltd. is proud to be the distributor for Catco Universal Catalytic Converters. Universal Catalytic Converters may be used on most cars and light trucks on the road today, but to be installed on a vehicle they do in most cases require, specific cutting and welding of the exhaust system. In addition Universal Catalytic Converters are not recommended in some cases. If you are interested in the purchase of a Universal Catalytic Converter and are not sure whether the application is correct for your vehicle please call our knowledgeable sales staff for assistance.
All Universal Catalytic Converters sold by Discount Converter, Ltd. are factory new not rebuilt, they carry full factory warranties and are EPA and CARB certified. We also carry some OBDII Universals that are approved for vehicles in California.
Universal Catalytic Converters are governed by strict vehicle weight and engine sizes. When shopping for universal units please pay close attention to the limitations of each unit pertaining to the GVW and engine size of that vehicle. When you see a weight and engine size listed for a specific converter it means that cat will work on any vehicle up to that total weight or engine and lower.
