When i stop after driving for about a half an hour, I can smell eggs/sulfer coming through the airvents. I can smell it when i get out of the car too. I dont think this is an uncommon problem with maximas. I just want to know what the problem is.

 

your cat has gone bad i believe

 

Yes, I would be inclined to agree that you need a new catalytic converter.

 

A y pipe wouldnt fix that problem right?

 

 

No, a y-pipe wouldn't fix the problem. You already have a y-pipe by the way. If its not the catalytic converter, it could be the dreaded foofoo valve problem.

 

Yeah i know i have a y pipe....i am getting a warpspeed in 2 days and thats why i asked, but i understand it wont fix the problem.

 

do you have a high flow cat or is it the stock one?

 

Its a stock cat

 

hmm how many miles on the car?

 

your cat is bad, you need to replace it.

 

Cystum Max - how long do stock cats usually last?

 

good question, i am not sure, My car has a bout 75k miles on it. I have a y-pipe. I am thinking since nissan designed that Pre-Cat, when you add the Y-Pipe that shorten the life of your regular Stock Cat.
But then I am not a expert on that. MIne has not gone bad yet. But I am waiting to see..

 

oh - very good point. maybe thats why some high flow cats die quicker?

 

i just got an RT cat in a deal when i got my catback but i just read a bunch of bad reviews about it in the FI forum. If it does die you think it would be a good idea to get a stock one again?

 

I have 130,000 on my car

 

my guess is that its very possible that it could have died w/ that mileage

 

My max does the same thing. How much is a new cat? Maybe I should just get a Y-Pipe and full cat back...

 

ive heard cats run about 80-100
catback would be cool too........
