the 1790 is a 2.25 inlet/outlet but it looks nothing like the picture you posted in your OP... do you think it will work the same? it looks like a slimmer version.
Yes 1790 is for stock piping which requires a 2.25 piping. Remember your midpipes are smaller so the amount of cubic air flow coming through into the piping will be proportional to the size of the resonators. It will work identically to the 1792. I wouldnt worry about that.
