    The DEC catalytic converter features high quality and provide unparalleled performance. The company offers replacement catalytic converters for various applications, including domestic ones. Domestic vehicles are not foreign to the company. DEC's specialty OBDII domestic catalytic converters are the parts that fit and perform up to the mark, and the company's long lasting warranty insures that a customer gets a cost efficient long term solution.

    The company has been the innovator of many things. It was the first to design direct fit catalytic converters. Carrying on a tradition of being first, the company is the first and only to feature a Cross-Marketing agreement approved by C.A.R.B. DEC presents the most comprehensive line of C.A.R.B. exempt, direct fit converters in the industry. These catalytic converters mimic the OEM part and ensure no welding involved in the installation process, just an easy bolt-on application. When utilizing a universal converter, you can't be sure that it will fit your specific vehicle precisely.

    Knowing what car, truck or SUV a part is being installed, DEC is the only company in the industry that provides TSB's and Tech Notes which you can use for your personal vehicle. Having years of manifold mount and close coupled experience, DEC is also considered to be a manifold converter specialist. Because of the location of the manifold converters, they require additional engineering to provide accuracy and longevity. The products of the company have been and are specifically designed and manufactured to comply to all specifications as they relate to emission performance requirements prescribed by the CARB and the EPA.

    Thank You
    CARiD is the first online parts store where the parts actually fit my car. I have bought the same part twice from other online retailers and have had to return it because it was wrong. And the part arrived faster than I Thought it would. So thank for not only providing quality but the speed in which it was received was excellent as well.
