    possibility you might get some backfire popping. Yeah you'd just replace it with piping, the "glass thing" you speak of is a glass packed resonator. You can get a straight one for a decent price to change the sound. It shouldn't reduce gas mileage..

    Just throw a piece if pipe in there...

    Pros: massive weight savings, better exhaust flow, at least 15 horsepower gain*
    Cons: very deep hum at low rpm (solved with nice muffler)



    *after removal of cats, muffler, installation of chip/software

    Chicks dig things that hum, just not cars.

    Removing the resonator causes uncomfortable audio resonation at certain RPM and cruise speeds. Maybe you could live with it. However, your passenger may not.

    The OEM resonator does a very good job limiting unpleasant resonation. It's just that the damn thing weighs around 40 lbs.

    It's your call to what extent you want/like/viscerally need an engine hum at crusing speed.
