high-flow cats
Can anyone recommend a good high-flow catalytic converter which would utilize the air tube running to it on my '83 GSL? I didn't know if the stuff in the usual Jeggs, Summit, JC Whitney, etc. catalogs could withstand the high temps of a rotary engine.

When you put it in, design the system in such a way that the cat can easily be swaped out for a straight pipe. Then you just put the cat in for testing purposes, then remove it so it stays good until the next test.

Thanks for the suggestion... I can't imagine how loud it would be w/ a straight pipe. It's bad enough with the POS Pace-Setter header and muffler on it! I'm curious to see how much power can be attained while leaving the emissions intact.
Someday when I get a new carb, I'll ditch the EPA ball 'n chain.

The interesting thing is the engine will make 100hp peak with the stock manifold and converters, while it will only make 90hp with the Pacesetter and no cats. The pacesetter truly is garbage.

Peejay has the right idea. No cat on the market that is high flow will last more than a year and a half if you run headers. I had a Random Tech cat for big cube engines that lasted two years. That is a personal record. I don't spend more than $80 on a cat now. Even the generics have the honeycomb matrix, which is what you want to see when you look inside it. With the air tube and a system that disengages air supply at 3000RPM, the cats aren't lasting more than a little over a year with continuous daily use. Essentially, I have had to replace them every year for inspection, now that I dwell on the matter. I have a conscious, however, that won't let me be a gross polluter...you may now begin to flame me...

I'd still like to find a freer-flowing cat though!

All of this is fine and dandy, but correct me if I am wrong... RB is the best hands down from start to finish... from header to tip...
My questions are...
1) Is a full RB exhaust emissions legal.
2) Is the HP gain that much?
3) Anywhere I can find it cheaper than $500 for complete system?
4) If I don't get a complete system, whats the order I need to buy the pieces (12a)

this highflow cat bolts right into your rb headers..... I have one....

Is there an aftermarket cat that would bolt in to the same location as the presilencer on my RB system AND stand up to the heat produced by the rotary?
Just curious,
