| no muffler
i have never had a issue with the dealers, i had a warr. issue that my duramax not driving right, took it in and i was asked if i had a chip in it,nope,have i modified anything, nope, i told them that the only thing i have done to her was i cut the muffler off and they said that that was not a problem. now cutting off the cat, thats up to you but i think the cost of that ticket would not be worth it to me.
