    if the car your about to buy has under 120,xxx miles on it the cats are still under warranty so you could get gm to replace them or good excuse to buy some headers and do away with them if you can.

    My M6 vert's exhaust (stock) sounds blown out on a cold start... as soon as it warms up it goes back to normal. I'm guessing this is my cats... but I haven't noticed a power loss.

    some people have told me cats are warrantied for 10y or 100k, others say 8/80 and I've even heard 7/70... I'm still doin the research myself. I know Mass state law is 8/80... and RI usually has the same laws. I would call a dealer, they'll run your vin over the phone and tell if its covered.

    8/80 was the original federal emissions cat warranty, in December '06 GM sent everyone a letter extending it on the 00-02 F-cars to 10/120. Bad cats will usually throw the SES for P0420/P0430 depending on which bank. Masse Pontiac needs to put out the correct info....
