Exhaust Smell.

[PeNZ]

Sup guys ive noticed that my exhaust is starting to smell like rotten eggs. Im not getting any troubles with the engine stalling or anything. Is my cat on its way out??

It's the cat. If I were you, I'd just go 2.5" while your replacing it.

Shiet those are too expensive.

Find out what killed the cat. They don't just die, something's not right with your motor, running rich or lean.

Too bad you have emissions by you, otherwise I'd say hollow that thing out.

[cutlass1991]

you might need a new oxygen sensor. My car stinks and gets shitty gas mileage, so it's kind of obvious that it is running too rich. I thought it was the cat, but my car just passed emissions by a very wide margin. The guy at the shop told me it's even better than some new cars. But I'd say check the O2 sensor before you buy a new cat.

Why are you smelling your exhaust in the first place? thats just weird. :shock:

 

j/k anyhow, change the cat and O2. the cat is 10 years old now, its probably due for changeing as is the O2 sensor.

I often lock myself in the garage and smell the exhaust just to make sure everything is running properly.

Are you serious?

I'm thinking sarcasm is in order here...lol

 

Anyway, my Lumina has been doing the same thing, and we replaced the cat last year too. So, would the O2 sensor be at fault, and how much are those things?

$30 ish...

 

Cars are powered by computers. Need I say ANYTHING more?

 

After time spyware, and virus' clog up (bad sensors) .... any more of a dumb way to explain it?

When I did my exhaust, I added a carsound cat I bought for about $40, it smelled kinda bad for the first couple months brand new. Kinda freaked me out, I thought the engine had a problem, but it turned out fine, and the smell went away.

 

I just cut the entire down pipe off my car, if you want the cat, it was used for 11months, and about 1500miles. Im building a 3" DP w/o cat for the turbo so i have no use for it now.

my Z was doing that too, before I changed my O2 sensor... it also made a coffee been smell, and a watermelon smell and a strawberry smell.... that's freaky

 

and mine's 12 years old
