running a different exhaust can definitely affect backfiring ,it may be drawing un burned fuel back in the pipe causing it to pop in the pipe
Polaris 488 fan backfiring
I have a 488 fan it runs great until it gets really warm then it will start backfiring and losing power once I top it out I don’t have any problems.

Any ideas could use the help thank you
