The Aftermarket Option

Exhaust after-treatment systems for medium duty trucks, buses and heavy duty class 8 trucks, model year 2007 and newer, are sophisticated and heavily integrated with the engine and ECU. Until now, no aftermarket systems were available. If the system failed after the warranty period, you would pay for another OEM system. Prices were high simply because the OEM part was the only game in town. That was until now.
After years of development, We now offer a complete line of aftermarket emission control systems for model year 2007 and newer medium duty trucks, buses and heavy duty class 8 diesel trucks. The particulate control systems are available for all major truck manufacturers and built to equivalent or better standards than the OEM system.  All the systems are tested and guaranteed to work with your truck engine the same way an OEM system would.
