i have an 86 N/A and im in need for a cat. converter. which is the best for performance?. also , what are some sites to get them. thanks

 

I replaced my cats with the Bonez power-flo pre silencer & cat. Is a direct replacement. Pull out you cats and bolts right in. Good performance gains and still pass emissions tests if necessary. Can get at Rotary Performance at RX7.COM.

I know several people that have the Bonez Cat and they love it. I personally run the Bonez race pipe since I don't have emissions testing. That Cat is at RX7.com

Ya you should get the Bonez precat replacement pipe/cat combo & also later on u could get the straight racepipe & swap them for emission testing.
