An exhaust for an FD, with factory cats or high flow cats on it? That I could borrow and/or buy? I want to try and make my car pass emissions. It might be a futile endeavor given that my car currently has NO emissions related equipment, but I'm so tired of seeing it sit in the garage and not being able to drive it. I'm hoping that with two cats, an air pump and a good tune, it'll pass.

Also, does anyone know if a stock exhaust will work? With my setup, I'm pushing more power than stock...I know the factory cats have problems with getting clogged even on factory cars...

I have my old stock exhaust in my storage unit. I'm not sure where my stock DP is though. And you could always just take off the stock exhaust after passing emissions HAHA.

Rotary engines kill catalytic converters two way;

-high exhaust gas temperatures can literally melt the cat from the inside out.

-rotaries burn oil by design, and most people who run more power than stock also run more oil than stock, so naturally some oil will not get burned during the combustion cycle. Thus hot oil is forced into the cat and can kill the element inside. (This is also why rotaries hate passing emissions LOL)

You can certainly run a cat, but I wouldn't do it for long. Once you pass emissions pull it off.

I'm probably just going to get this:

Has a spot for the airpump, I'm thinking with that and a good tune I might pass If not I'll throw another cat on and hopefully that helps haha. Reallllly don't want to cut up my RB catback though.
