If its the stock cat on a S13 its most likly gone. You could also be running terribly rich. ---

Clutch doesnt really smell like eggs IMO more like your brakes after being on the track for 20min. ---

Rev match, and work on you clutch skills. If its not the clutch, likely you are running rich and fuel is burning inside your cat. ---

For the cat the best thing to do is go stand behind your car and literally smell the exhaust. Get someone to rev and see if the smell is coming out the pipe. If you think it’s the clutch do you notice it slipping? I.e. if you take 1st gear high into the revs than shift into 2nd do you notice your revs stay up and then fall down as you’re accelerating (like the clutch is slipping instead of gripping) ---

Check your ECU coded might be a faulty sensor.
