I have a question ,I have a 4.2 running 2 1/4''exhaust without a cat with a glasspack and on cool days when I let off the gas to slow down it back fires alot, I use to run a turbo muffler and it didn't do it then will this hurt my baby or should I not worry about it thanks for any input. :roll: :roll: [addsig]
