As far as I can tell a "BP Miata 1.8" is from '94-'97 or so. That is one of the things I have to nail down before I order or I'll be up the creek.
I'm also thinking of buying a decent high flow catalytic converter to nix my P0420, and 2.25" pipe all the way back, with a quiet but free flowing muffler somewhere in the middle, as the rest of the exhaust is well past its prime. My concern with the high flow cat is that it may not be efficient enough to kill the code as it will be a fair distance away from the exhaust ports and may not get sufficient heat to work as it should.
On a completely different tangent, has anybody considered making a snorkel out of a turbo piping kit? Cheap, cheap cheap on ebay, with elbows and clamps and whatnot, in sizes up to and including far larger than anything you'd need for a 2.0l. I'd be all over this if I didn't have plenty of other things to address before I start modifying my perfectly functional intake...
