It always backfires when i shift just before redline

!! I think it is because of the headers and the race cats!
Even i never knowed that before.. we just discovered that last week
Sorry i am not THAT technical.. how should the ground wires protect the car from backfiring?? Its just the overdose of petrol which is there... comes than into the hot exhaust and BOOOOOOM... beause there is nothing what could hold it off like cats
