I was browsing RB's website because I'm going the N/A route and wanted a good header, but they have four different RB headers!

I don't know which one is best for me Do these bolt up to the stock exhoaust? And while we're at it... What better the CorckSport 13b Header or the Racing Beat 13b header? Thanks guys

 

They have headers for a 6 port, P-ported engine, and like a street and a track header. I like the Racing Beat stuff, they've been doing it for years and know what's going on. I'd go with a RB header.

 

Thanks for the reply. I have an S4 model RX7, I would like the street header I'm hoping that it has the necesary o2 bung as I do hope to still pass emissions. Also doesn't the RB design sill open the actuators at the right times?

 

Since you want the street collected system, you will get the collected header. You will also need to get the s4 presilencer for it to mate up with the rest of your exhaust. This is the device that opens the aux ports. If you need to pass emissions Bonez makes a cat that bolts up after the header that allows you to pass emissions, but I don't know if it works the aux ports or not. You can ask www.rx7.com about it since they are the ones who sell the cat.
