Exhaust smells like sulfur

I have a cone intake with a k&n filter with a heatshield. Other than that my car is stock, but I do know that my O2 sensor is bad. Would that have anything to do with the smell? The car is a 93 325is, what do you guys think? I have to smog my car as well so I know I'm gonna have to pay for that sensor to replaced and I've see them for $180!!

here's a pic of my intake

It must be hard to hold the reigns back of that 400 hp monster, Damn if I had that beast I wouldnt be able to only drive it 15k miles. I would want to drive it all the time racking up double the miles at least. Awsome machine it is

Does it only happen after you've been driving the car hard? Cause sometime the car will fart when you stop after driving it hard or when you use CHEAP gas from "Penny petro" or some low grade high sulfer gas.

when it farts just let on that it's the other guy.

The sulfar smell has nothing to do with your cat, all the cat does is add oxygen to the HC's and CO and remove it from NOx. CO and NOx is odourless, and HC is unburnt fuel.

The problem with the smell is your using a gas with a high sulfar content, just try different gas.

You'll have to replace the O2 sensor through for the e-test, since without it, the computer isnt able to control the secondary air system properly, with will affect your emission readings

On my last e36, the bad exhaust smell went away when I installed a performance chip, and switched to premium fuel, but on my current E36, I only get the bad sulfur smell when I use Esso gasoline....everything else smells fine.

Try a different brand of gas (and premium) before spending hundreds on things you may not need

(now if only I could get rid of that burnt clutch smell, my car would be 100% )
