DEC catalytic any good? "X" pipe? (archive)

Has anyone here used the DEC brand catalytic converter as sold by Steve D. at Ultimate Garage? Steve drop ships them so has never actually seen one and isn't sure if it has the cross-over "X" pipe (looks more like an "H" to me).

From what he hears it flows pretty good, but still prefers the factory unit at over 3 times the price.

For $550 it's affordable. One of my cats has rattled loose internally and needs to be replaced. Has anyone just repaired their existing pipes with a matched set of cats?

I understand that a single cat back without crossover is a no-no unless one has at least an Evo 2.5L to push the exhaust out hard enough to prevent backdrafts.

Is Mario Langston on this list? His website ( ? ) used to sell an aftermarket cat with dual cats and cross-over. There are pictures. Was it a DEC unit? Is Fillipo on this list? My ///M3 is also painted conspiracy theory Hennarot.

Looking for a catalytic solution - hope to hear from you guys.
