Why Are We Legal?
Customers all over the country, and now specifically in New York are aware of the fact that DEC offers the most complete line of C.A.R.B. exempt, direct fit catalytic converters in the industry, yet they are wondering why they cannot find DEC listed on the CARB website.

DEC has been the pioneer of many things. We were the first to make Direct Fit Catalytic Converters and keeping with our tradition of being first, we are the first and only to have a Cross-Marketing Agreement accepted by C.A.R.B.

Below is a section of our cross-marketing agreement with Magnaflow / Car Sound which shows the accepted arrangement.

DEC continues to build strong relationships with all manufacturers of converters in the state of California due to our unique position. If an application is found on the ARB website then DEC can make the part. This puts DEC in a very unique position and through cross-marketing agreements with each manufacturer and allows us to purchase C.A.R.B. exempt products from many manufacturers and then turn them into the finest direct fit pieces anywhere in the industry.

DEC does not make universal catalytic converters, we only manufacture direct fit catalytic converters, so there is no welding involved, just a simple bolt-on application as if you ordered from the dealer.
