Anyone running a cat? If so what kind can handle the heat?

 

I have the Bonez high flow cat from RX7.com. People have had trouble ordering lately though.

 

I have a metal substrate GESI cat. Allegedly hold up to the heat better than ceramic.

 

Can you tell me where you got it?
I’ve given up on RX7.com

 

I'm on my second Bonez Street Performance System for the 1984-85 RX7 GSL-SE, the first one lasted over twenty years, which is longer the the original OEM catalytic converters did. It's "plug-and-play," and has the required port for controlling the 13b auxiliary ports however, like Toruki mentioned in his post, people seem to be having trouble placing orders lately.

Most speed shops carry it, my issue is I bought during pandemic and I tried to purchase through multiple shops, all ended with cancelled orders . Bought a Kooks which is a rebranded GESI with the honor of having “Kooks” attached. Guess it’s a big name in quality with the v8 crowd.

a problem I see is there is no air injection on these cats. And expensive. About $650 depending on vendor. On the other hand, probably the second best you can get next to HJS which is twice the price.
