You don't need that H pipe crossover chamber. I have individual pipes and I didn't even re-jet.
But I do believe it contributes to more decel popping, at least on mine. I have richend the pilot jets not long ago to see if it would help, and it still has A LOT of decel pop.
I think the factory chamber has a lot to do with equalizing some of the exhaust gas pulsation and can soften the popping.
I remember back years ago when Dual exhaust was installed on the old V8s, they would weld in a crossover to lower the popping/ backfire. More of a mellow sound.
