Tighten up your exhaust flange bolts. Go for ride tighten them up again. Might need to do it a couple times. When pipes are hot they will burn you watch out
If the bolts get tight and it still does it you'll need new gaskets

Just a leak will cause all that backfire? No other issues?

Vics seem to back fire. Two bought new they did it stock but quietly. They have both been dyno tuned with programmers and timing wheel they still do it some. another one bought used with stage one and pipes back fires some. Don't close throttle all the way on decel will all but eliminate it. Not fact but that's how it is here. Good luck hopefully someone will chime in with real answers.

You should call it an after fire, not back fire

how about just popping out the exhaust, to many people get all bent out of shape because we call it backfiring, its not a super technical thing. try unplugging the O2 sensors.

If you use the correct words to describe your issues, then you can get the correct answers. A backfire is when it fires back through the intake

I did not know we were addressing your problems to.
Like I said tighten your flange nuts go for ride come back retighten them. You might have to do it two or three times.
