Car exhaust stinks

Hey
My car exhaust stinks, it smells like rotten eggs or like sulphur. Not exactly how to explain the smell, but what could this mean? A new cat?

Thanks

need new cat… meow

yea meow cat now

whats the best cat to get?
magnaflow- 2.5inch? , Car is Stock

any other recommendations?

no cat ? lol straight pipe, magnaflow 2.5 will do the job since its fairly cheap and the car is n/a

I had a 2.25" magnaflow on the altima no complaints… I paid around $75 on sale at part source

take the dead racoon out your rad
