    aftermarket catalytic converter

    I need to replace the catalytic converter on a 98 STS. Does anyone
    know what brand, size, or part # is needed to replace this cat. I want
    an aftermarket cat so I can have a custom exhaust set up. I'm thinking,
    new cat, remove resonator, and dynamax mufflers. All thoughts greatly
    appreciated.

    Call a parts store. They can tell you all that stuff and they can also tell you how much it is.

    I'd leave the resonator in if I were you otherwise it will sound like your car is powered by thousands of bees with all the drone you'll be hearing.

    Re: aftermarket catalytic converter

    i went with a 2.5Inch magnaflow hi-flow cat converter, it completely enhanced my corsa exhaust tone. I love it, deeper tone, a little more torque . Its a universal for a 99 STS,. and this is what they gave me. I suggest this one.
    i also went 2.5 so it matches the 2.5inch corsa...i dont want the car too loud. right now its perfect.
