Hi, I'd like to keep my catalytic converters because I live in CA. I have an 87 RX-7 N/A manual transmission coupe.

Do the Racing Beat headers bolt up to the stock catalytic converters? I'd like to have aftermarket headers, my high flow cat (which is in the stock position), and a catback.

I'm specifically looking at the following two headers:

http://www.racingbeat.com/resultset....rtnumber=16131

I know the Corksport headers do bolt to the stock cats, because the website says so (about half way down):
http://corksport.com/store/category/...rx-intake.html

Racing Beat's site talks about using the headers in combination with their presilencer, but they don't say if they will bolt up to the stock catalytic converters.

However if there are any other Racing Beat headers or another company's that would fit my application, please let me know. Thank you very much!

 

No, they do not bolt up. The only header I can think of that bolts up to the stock cat is the corksport header. Bonez also makes a cat that will bolt up to the RB header, its available at www.rx7.com

 

Thank you very much for your reply, thats exactly what I was looking for. I've got an aftermarket high flow cat, but I don't know the manufacturer of it. It does however bolt up to the stock downpipe.

 

You CAN use the stock main cat with an RB beader, you just need to get a small extension piece made up to fill in the gap that's left when you bolt them together.

 

Oh ok thank you. I was under the false impression that the headers were too long, not too short. Thanks!
