Cats going south more often than not smell like rotten eggs, or start rattling out of the blue when the stuff inside them breaks up.

It stinks i know that much and i dont really smell it alot but when i get on it are drive it hard i get this wired smell..

Maybe now is the perfect time to swap in a nice midpipe then and forget about those cats...

Problem could be a lot of other things other than your cats...but if there is a weird smell, then yeah it might be the cats. Take em off and inspect them.

I would not think it is your cats until they start ratteling

When do you know your cats are bad?

If they're peeing all over the carpet, scratching everything up, spraying/marking the walls, pooping outside the litter box, looking at you like you don't know **** and never obeying a word you say, tearing up the curtains in your living room and so forth.. damn furry, mischevious little animals..

Oh wait, you meant catalytic converters

Not quite sure on that one

they start smelling or rattling

also because of the heat they generate when they are clogged they might glow red after you turn everything off, not kidding

Pretty sure bad cats would throw a code and trigger SES light.

Cantslowdown · Feb 26, 2006

They dont glow but it dose smell wired..I have checked to see if they glow and they dont.. But yes the cats are going to come off here soon just wanting to see if this is the problem are not.

Mike97gt · Feb 26, 2006

yeah i too have seen them glow red when overheated. you guys do have to remember when you get on a car with cats you will get some smell out of the tailpipe. the cats are tuned to deal with emmisions of a motor running at or near stoch. at WOT the mixture is richer so you get a little smell. not rotten eggs it's another smell. the rotten egg smell is from sulfur in the gas.

you should not have any smell during normal driving. it is possible your cats are starting to clog up.

Cantslowdown · Feb 26, 2006

Thats what i was thinking but i wanted some more info b/4 i put a new mid pipe on..

Cantslowdown · Feb 27, 2006

Welp i figured out if i dont run it hard i dont smell it and if i drive it hard and say stop and get out i smell a wired smell..

Mike97gt · Feb 27, 2006

if you are getting on your car or driving aggresive for awile you can overheat the cats. maybe thats what your smelling. they probally are on the way out.

Cantslowdown · Feb 27, 2006

I think its time to kick the cats to the curb!

webslinger67 · Mar 20, 2007
