    1998 Catera needs new Muffler- cannot find one anywhere- Please assist.

    Hi
    I have a 1998 catera and it needs a new "Resonator".

    I cannot find one on rockauto, partstrain... and so on.
    Do I really have to go through a dealership for this?

    Note that its on the back-left, 2 inlet and 1 outlet- but I have not measured the mfg diameters yet.
    ...just called the Stealership and they said it's called the "Resonator" and they want $500+

    Any suggestions will be appreciated.

    Im confused.
    Please assist.
    the dealership is calling it a resonator...
    but its really the muffler (for all I know)
    It's near the drivers rear tire, it has 2 inlets and one outlet.

    Here's a parts diagram.

    You could always try a local junkyard.

    Crawl underneath and ahead of the rear suspension you'll see 2 rectangular (sort of) canisters. Those are the true mufflers. The box at the rear is a resonator. It's internally divided to maintain a true dual exhaust. All Cateras have 2 outlets from the resonator so it's possible yours isn't stock. You could eliminate it if yours is damaged but I don't know how that would affect the noise level or exhaust back pressure. Measure the resonator and find a free flow muffler of roughly the same size if the noise is objectionable.

    Below is a link to a pic of the Steinmetz exhaust system but you get the gist. The 2 canisters are the true mufflers.

    Thanks Guys.
    Based on this diagram http://www.gmpartsonline.net/parts/1...iagram=BK97123
    What I need is part #3. The resonator.

    But now is really doesn't matter any more because the shop that was installing new motor mounts on my car, had 14 cars targeted/14 catalytic converters stolen from cars and MINE WAS ONE OF THEM! I just had comp./collision on this old car, and the shop said their insurance does not cover their lot- so Im f**ked. Good thing I got it to pass emissions before this happened!~ So without a Cat. Converter, it will not pass emissions in two years anyways! Danmed if Im going to put another 1500 into this money pit! I'll try to get it through this WI winter and then trade it in, or part it out come spring! What a "Sofa King" nightmare this car has been!

    If you left something in the car that was stolen while it was at the shop for repair, I might see there is an argument that the insurance doesn't cover that loss, but they are responsible if a part of the car is stolen while at their shop for repair - Small claims court and /or State Bureau that regulates Automotive repair
