Hello how are you, my question is that the Apexi super catalyzer it is compatble wit the RX-7 FD3S year 93?

 

I believe so. I don't think anyone here has ever used it. It's overpriced for what it is.

 

I think the Bonez high flow cat (it is the 2nd picture down) is a great choice:

I'm with Rich on this one. If I were to use a hi flow cat, that would be the one. I think I'm going to go catless though, and use a resonated midpipe, and make every two years a hunt for a smogcheck haha!

 

I don't see the Bonez being a high flow or much higher flow then the OEM cat' since it uses the old dual brick with air pipe in the middle just as OEM does. It is half the price of OEM however. He could email Apexi since he is long distance.

 

I wonder if he even has to pass smog where he is at. Hey GoRacer, how do you like your turbo? Really quick spool? I want to go single, but I'd like a super fast spooling single! haha!

 

Well I would recomend the smaller .85 A/R compressor snail which starts at 2850rpms which is less HP but should allow you to use a Hyper single instead of a twin plate which has a heavier pedal pressure, if you drive in any stop-n-go traffic that is. Mine kicks in around 3200 and is pretty much instant full bost up to about 7k rpm's. I think that's the highest i've gone (too scared to redline). My turbo thread "here"

I would assume that Knightsports hi flow metal cat would be just as expensive. Most likely his shipping maybe just as expensive as the product so might as well get the best one.
