    Default 12' Chevy Captiva Sport V6 - Muffler Rattle

    Finally took my truck into an exhaust shop to look at possibly getting an aftermarket setup due to this issue, and the fact that the Dealership near me wouldn't do anything about it.

    The exhaust shop said that there was a spot weld for the heat shield that broke. I'm going to take it to the dealership 1 more time before plan B (cut the B**ch off and run a straight pipe from the axle back)

    Anyone know how a straight pipe would sound on a 3.0L V6?

    duals will start with a Y pipe at the rear axle. Was thinking about rigging up a cutout to use for the 1 side, and put a muffler on the other. but thats illegal in the state of VA.

    UPDATE:
    Appointment Saturday morning at the stealership to diagnose the part. then order the replacement. since the stealership wont just tack weld the piece back on. So they're going to waste a whole bunch of time and money to replace everything from the manifold back because it's all 1 piece. I even called GM corporate to ask them if I can take it to a muffler shop and have them send GM warranty the bill, and they declined that. It would certainly be quicker/cheaper to have that done than to just replace everything.

    oh well, at least they give me a free car wash.

    RESOLUTION!

    Dealership replaced the entire exhaust system from the flex pipe back (all 1 piece) and now the rattle is gone.

    Warranty spent over $1K to replace all of that. Glad it wasn't me. But I would have rather cut the B**ch off and straight piped it for $200.

    Not to mention my passengers legs will be nice and toasty.

    Still going to keep the duals out the back, just going to eliminate the 2nd muffler under the back of the storage compartment.

    I'll be happy because it's gonna be LOUD!!!
