Damn! In that case i might go with a Random Technology Catalytic Convertor + a Cork sport header. The RT cat should bolt up as should the CS header. RT's cat should (in theory) do the work of 20 year old cats.
yeah the thought of buying a 475 converter just so somebody can use RB headers is kinda ridiculous
shoot you can get a magnaflow converter , a midpipe, and have an exhaust shop cut/weld everything up for probably Half the cost of a mazdatrix header converter!
of course some people might say using a converter with headers is also pointless.......

Actually...I think I might say screw going n/a if I won't be able to pass emissions 
I might stock turbo swap it and call it a day. Staying n/a would be easier if I could pass emissions. The CS header is $300 and the RT cat is $250 I can't justify that money used for a few hp, when I could put it towards dropping a stock 13b-t.

I know but I live in Massachusetts; got to pass the tail pipe. Todays high flow cats are actually really good at not robbing hp. they're very efficient.

New Product release from CorkSport, the Power Series N/A Header for the 86-91 Rx7. The Power Series Header is made from 304 SS and bolts up to the stock cat on your Rx7. This header is in stock. We dynoed the header on a stock 1990 Rx7 and gained 14hp
I have to pass emissions again in like 2 years. I think I'll just get this put it in myself. try to pass emissions down the road and if I don't I'll blame the cat and get a newer more efficient piece

header fails the visual if you have it. as far as actual tailpipe emissions the header seems to actually help a little when everythings hot.
todays highlfow cats maybe flow a teeny bit more than the stockers, but they wont last half as long

We don't have visual inspection in MA, They check for leaks and then run the tail pipe that's all. We don't need CARB stickers or anything.

Really?
Thinking about this more deeply, I'm going to continue with the n/a build as fuel management should help keep fuel in check and a header will run a little hotter and burn up fuel before it gets to the main cat. I'm going with Corksport as it bolt's up to the stock cat.
