Is it stock or aftermarket. Do you have cats or not. Tell us something so we can help.

Do you have the Borla exhaust w/ the straight thru pipe? Mine stunk like skunk **** until I put the plate in that diverted the flow thru the muffler instead of a straight pipe and the smell stopped.

like they said.. if you still have the cats and that many miles.. odds are that the stockers took a crap and need replaced. They will smell horrible.

'99 w/ 110K...I bet it is the cats. Who cares what it smells like behind you. I ditched my cats completely and all I smell is normal exhaust/a little bit of fuel. I don't understand the rotten eggs smell. I run LT's to ORY to catback and don't smell anything. Is this a clogged cat smell or something where the catalyst is getting really hot and breaking down and smelling?

"Why does my exhaust stink?"

Could it be your diet? Now, as to why your car's exhaust might stink, well that would probably be the catalytic convertor.

I have hooker lt's, ORY, and nothing but a crapmaster muff on the back.
I can smell fuel burning on my car (depeding on wind direction) If i'm sitting still, and no wind i can't smell it. If i back the car up from a stop i can smell it.
It's just the lack of a cat.
I think it's a great smell. I dont mind it at all =)
