Backfire is normal?
I had the stock exhausts on there with the catalytic converter, cut out the converter and put some brand new racing beat exhausts and it pops loud. Someone said its pretty normal just wanna make sure?

State your car in future tech questions please...and less back pressure as you have no cat on it is usually what causes your "backfire"..
Now you just need stickers..Hotdogs flamedbroiled here ---->>>>> (tail pipe entrance..)..lol!

It's not running rich at all. I've set the idle properly.
The reason it backfires is not because of the mixture, but because of the age of the engine+an inherent flaw in the design of the Wankel.
If you aren't running a fuel injected engine, it still takes a sip of gas even though the ignition is turning off as the engine spins down. This little bit of mixture is more than enough to ignite when it goes over the exhaust.

Ideally...no. it's not supposed to.
I beg to differ. Back fires have a lot to do with air/fuel mixture.

Some backfires on a wankel when it's spooling down just after letting off the acceleration pedal are normal. I've never heard one backfire during warm up.
Low fuel pressure can cause this. Check fuel filters, pumps, and any other obstacles in the fuel lines.
Catalytic converter removal/damage will cause it. Specifically in the RX7 when an air injection system in the exhaust.This creates a combustion in the exhaust system and the the lower resistance of a damaged/removed exhaust allows the combustion to take place immediately.
An air leak into your intake can mess up your AFR and cause this as well.
