Default Re: engine backfire when slowing down

I am with 40 DELUXE, sit back and enjoy the sound, every car I had after putting on glass packs will pop back, my 56 to slow down I will pull down to low and she will really crackle. also we use to block off the heat risers with pennies on the flat heads to get them to pop back.
