I heard that Fabspeed's sport cat will pass but it's double the price of most other catted DP's. But maybe that is the price you have to pay to get a pass with Massachusetts emissions standards.

Not sure whether this was ever resolved or answered, but I'd like to know myself whether we can run a catted DP in MA and still pass emissions without having to swap out every time
