Hi Flow Cat
 

I have a rx7 store midpipe with a T-78 turbo setup on an FD.

I was told without an airpump, most of the hi flo cats will
not last.

Any suggestions, or is importing some cats from Knightsports, Re Amemiya, etc
the only alternative? It seems they work without the air pump but are
very expensive.

thanks

Try N-Tech. They claim theirs works without an Airpump.

Thanks for the input.

The price is certainly reasonable.
I will give them a call this week.
