[align=left]Well i just got back from eating and once I turned off the car and got out I smelled rotten eggs again. I quickly went to the exhaust and it came from there. I'm definetely think its the cat now. My 02 LS had the cat replaed under warranty at 79K miles and it too smelled the same. It also ran like crap but all good when replaced. My gas mileage has gone down a bit alaong with the torque. At about 20mpg at 80% highway.[/align][align=left][/align][align=left]I never heard that its normal for the exhaust to smell, rj. I'll take it to the dealership and get it tested this week probably and see what they tell me. I also only put chevron. [/align]
