I am getting an oder of rotten eggs smell. However it usually only happens after I punch it to get on or off the Highway. any ideas. someone mentioned to me that it might be an O2 sensor.

The car seems to drive fine, and there are not lights on the dash.

 

it's your catalytic converter

 

Your cat is going bad.

 

the car is farting.. whats wrong with that?

ur cat is toast...

 

or it could be a bad egr valve

 

bad sushi...

 

meeeeooowww.!!!

 

Maybe you farted?


Seriously, your Meow is shot...

 

just cut it off and straight pipe it, i did that to mine lol and i got 40 bucks out of the deal when i sold the cat

 

are the cats on ebay any good? what are the consequences of having a bad pipe?

 

cats are good for environment and you dont get any gains from removing one, so just replace it, think of your future kids man

 

does it restrict anything? sorry for the noob questions

 

barely, but you can get a high-flow kitty and not worry about that

 

Told by a nissan mech. that it is unburnt gas burning because of high heat
