76,xxx. What pi$$e$ me off is I just bought the car Dec 4th. This all started happening Dec27th. The Dealer agreed to put the header and downpipe on @ no charge when I found out the cat was bad. I don't know what they are gonna do about this. The car was used/as is but c'mon....I didn't blow the thing up in two weeks(drove 4x4 other week in snow) Gave me an estimate of 3k to replace 1 piston ring. This is without taking anything apart yet.
