Re: po420 and po430

GM had a cheesy catalyst media when they first started using Cats, but the media used now is pretty techno-savvy. Whereas the early ones were filled with a palladium-coated ceramic-type ball-shape, the later ones look like honeycomb and are fairly complex in their design. If you look at each end, you'd think that it is a straight-thru flow, but it isn't. The media isn't heavy, but stick it inside the shell and it gains weight.

Hope it all works out for you.
