D.E.C. Catalytic converters

[bmwstephen]

anyone have one of these? looking for some feedback here. I'm getting mixed results but supposedly they are the best of the aftermarket brands and recommended by Steve @ ultimate garage a while back.

CA emission requirements doesn't seem to allow even OEM cats as of Jan 2009 and have updated CAT requirements that only aftermarket companies can fill.

Bonus if you have the CA-legal version

supposedly bolt on. their reputation is associated with OEM cat supplier/manufacturing.

However, I've heard mixed results with their california cats... so I'm hoping someone can chime in. Their 49 state legal ones are supposed to be better than OEM design because of their stainless steel construction as opposed to the cast of oem
