Any of you FD owners (specifically California), replaced your stock main CAT with the Bonez High Flow main CAT? I have a 93 VR with an M2 downpipe and HKS CAT-Back exhaust, and was wondering if I installed the Bonez CAT would I still pass SMOG. I usually take my car to a local gas station that is not really familiar with RX7's for the SMOG and I pass every time. I just make sure that the engine is well warmed up.

 

If you search the "West Forum", you'll see people have passed emissions there with hi-flo cats, and more specifically the Bonez.

 

Great Thanks for the info.
