    My initial guess would be no, as most likely the 8.1 would need a larger diameter pipe and larger muffler, but you never know. If you had the part # and brand of exhaust for your particular 5.3 burb it would help alot.

    It could be made to fit, but it wont be a direct bolt on swap.
    You'll have to do some fabricating,
    You'll be better off buying a new system specifically made for your new truck.

    they have these things that make the mufflers inlet diameter bigger, but your better off with a new exhaust.

    Won't fit, just spend the money and install a new one, most exhaust shops do not want to help you, they hate messing with old pipe:great:
