DEC Catalytic Converters





For over twenty-six years DEC has been manufacturing a wide assortment of replacement catalytic converters which perform efficiently and correctly. The company also offers premium DEC headers, tailpipes, exhaust pipes, and more. All products by DEC are assembled in dedicated Steel Jigs utilizing heavily loaded substrates, heavy duty tubing, silent flex tubes, etc. DEC's unique concept of Steel Jigs for every model insures repeatability and perfect fit.

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.

Fit
Part meet California standards, but I don't know if was mishandled by the transport carrier, when I trying to install it the left tip towards the header didn't fit by almost one inch, so it cost me a 100.00 at a muffler shop have them to correct the pipe and make fit.

Fit Perfectly
Thieves stole my OEM Catalytic Converter. In desperate need for a replacement I was relieved to find this part. I was hesitant at first since this Catalytic Converter was priced under $200. The part I received was slightly different than what is pictured, CARiD customer service was quick to respond to my inquiry and guaranteed the part to be an exact fit. This part fit perfectly and installation took less than 2 hrs. Very Satisfied! Now my Element is back on the road with no exhaust issues.
