Weird Smell

Recently Ive been driving for shorter distances, driving normally, and when I get out I have a weird almost burning smell from under the car. Its not the brakes(Checked all for heat and pulled wheels for inspection). It seems its almost exhaust. Car runs perfect, pulls nicely and still getting 24mpg city. Any ideas?

Nope. I really can't say what it is. I know it's not burning brakes, oil or gas

Did you check underneath to see if anything got picked-up by your exhaust (i.e. plastic bag or road debris)..??

Yep, everything is clear. I washed it after every snow storm, undercarriage and all

Sulfur? Mine runs great but get the sulfur smell, an at times it doesn't smell like sulfur..it's weird smell.
an no warning lights or codes..if I take off quickly it's there for sure..but like said sometimes it doesn't smell like the Cadillac convert...it's different...

Yeah it could be the catalytic converter but they usually give a code. Check your air box (if you have one) for animals. And also the cabin air filter probably wasn't changed.. could be that if you smell it inside

Did all that, brand new k&n for outside, acdelco in the cabin. No codes either. All fluids fine, oil/coolant/brake. Has my mechanic baffled too.

Is it the carpet? Or maybe something under your seat or carpet.

na, its on the outside. If you stand in the front or back, you wont smell it at all. only on the sides. So it seems to me that it could be somthing with the exhaust. Im probabally replacing it soon anyway, but Im going to get it looked at,
