Sulfur Smell In Exhaust
2018 2ss with flowmaster axleback exhaust and k&n blackhawk cold air intake, no other mods. Mileage = 5600.
Lately, I have been noticing a sulfur smell in the exhaust fumes. It's not as bad as a rotten egg though. I noticed the smell when I had to get something out of the trunk and the car was idling. No CEL. I read it is the gas. I use 93 octane and I tried different brands. Same result. |

Could be the cats (converters) causing that smell.

Thanks for replying. I have my 7000 mile service coming up. I'll ask them then. Correct me if I am wrong, but if the Catalytic converters were bad or going, the downstream O2 sensors would throw a CEL, correct? Odds favor the Cats should be fine since they are brand new from the factory and I never touched them.

you may want to take k&n off put stock back on or they will try to tell you it's the air filter

Might not be the sensors but one of the cats as a defective or clogged cat could cause the smell.
