High Flow Cat Preferences and Preferred Vendors
Hey Guys
Just failed my Ontario Emissions test - worst numbers they have ever seen at my garage.
I could have sworn there was a whole thread devoted to this, but I couldn't find it.
What's the word on aftermarket cats and which vendors seem to be the most popular?

Thank you!
I know it will be harder to pass with a highflow - it seems none of the RX-7 guys are passing in Ontario, we're all getting conditional passes. The way that works is they 'diagnose' the problem, and if it will cost more than $450 to fix you get a conditional pass for two years (that's how long you have between etests anyway). But my car does reek, so I'm hoping a highflow cat will give me the same performance (I'm assuming my cat is shredded or something) and maybe upset my wife a little less.

+1 on the Bonez from rx7.com
For emissions, try and find a good condition, low mileage stock cat used or get together with the other RX7 guys and buy a new one that you can all use for testing purposes only so it doesn't get worn out. Use the Bonez for the rest of the year.
Make sure the air pump is working. Use 7 and 9 heat range plugs like stock. Use regular oil w/ low amounts of ZDDP for the test. It all helps.

That was my other plan.
It seems there may be some problem in shipping a cat cross border, but I'll have to look into that. I'll see if I can dig up a stock unit from someone local if all else fails.

I needed a replacement cat and noticed a Pettit cat for sale on the forums. If you need a decent replacement I'd say look for one used in the classified. It has the airpump hookup and is good to go. It's not worth it new lol.
A few years later I finally researched cell counts and metallic vs ceramic cores. I bought a used Knight Sports metalit cat after deciding on metallic. There is a ton of info on the forum/internet that will help you out.
