Well, it looks like you have a 99'. So any header would probably be a step up from stock. Raceland isn't exactly a "good" brand. May want to check out Installed my ebay Raceland header today - MX-5 Miata Forum for a decent review. I don't think it's worth spending the money for a RB header since you probably won't see much of a gain in power between any aftermarket header.

I recommend you look for a 2001-2005 NB2 OEM manifold. Its a significant upgrade from what you are running now and it will bolt right up to your current 99/00 factory downpipe. I know because I've been running like this for quite some time. It really makes a noticeable difference above 4,000rpm compared to the stock cast iron 99/00 OEM boat anchor.
See here: 2001 Tubular header
Remember you will need to change the locations of your O2 sensors to keep the factory ECU happy.

I have installed the race land header on a 1.6 engine, 1.8 95 engine, and a 99/01 engine and not a single one went in easily or fit the cat flange perfectly. I currently have the raceland header from the 95 engine sitting in my garage and it will not be going on my lemons car. Buy the 01+ OEM header and be done with it.

Because the "new" part is shittier than the "old" part.
For an OEM look, get the 01+ stock piece. The best thing about the 01+ is it's an OEM part. **** will fit (aside from the EGR tube, you'll need one from an 01+ car as well). It was made by a company who made hundreds of thousands of these cars. It works, they're all basically identical, no bashing with a hammer and a block of wood to make it fit. (cough, OBX header, cough)
I bought an OBX header, with the same midset you have. "It'll fit, it's cheaper than racing beat, win/win." Here's the aftermath.....

For the best OTS header, get the racing beat. After cutting the OBX out, the RB literally fell into place, sitting on the steering linkage. It fit perfect, the EGR fit perfectly, the gasket fit perfectly. Buy shoddy parts at your own risk. For midpipes and mufflers, talk to Enthuza.
