Header for Crx w/B16A

I have a 89 CRX Si that I just put a B16A in, and I wanted Chikara headers, unfortunately they don't seem to make headers for the B16A, theres no chikara header for the 99-00 Civic Si, nor the Vtec Del Sol. I wrote to chikara to see what they suggested, but a week later, no response. So it comes to you.
I know the header for any B series will bolt up, but my concern is will it offer as much benefit, like with the teg, since it is designed for an engine with more displacement, yada yada yada. Any help or alternate suggestions would be appreciated.

Header gains are so minute that it really doesn't matter. I like my 98 JDM ITR header just for the bling factor. I'm pretty sure that with the 2 1/2 collector, the flow is better than the next guy's DC sports but it still doesn't matter much. Just get something that'll last.

So you don't think the GSR header will be too big and weasle away the tiny amount of torque I do have?

As I've already said, I have a JDM 98 ITR header. They produce minute gains not rob you of power.

imma be running the DC header 4-2-1 1-piece on my b16a
