No it is not under emissions warranty the year is what is the factor, it is 7 years or 70,000 mile whichever comes first. You need the check engine fault code read and that fixed first, it is most likely the cause of the smell from the catalytic converter which is caused by a overly rich fuel air mixture. The fact you smelled the sulfur indicates the Cat is working. I was a certified repair and inspection technician for the Calif smog control program for 35 years.

You can Install ANY Catalytic Converters that you wish on the Car. There are only Sensors Before the Converters. The only forseen Problem that I can see is: Do you have Smog Tests in the Area Where you live???? If so, You may have no Choice but to Install the Expensive ones or it May not Pass the Emissions Smog Tests. Here in Oklahoma, We do Not have Smog Tests and can Run any Exhaust that we Want But, Not everywhere in the US Is like this. Please Rate My Response! Thanks!

If you want the check engine light to stay off, make sure that the converter is a direct fit, and not a universal. It should work fine then.

YOU REMOVE THE 4 BOLTS BEFORE AND AFTER THE CAT.
ENSURE THE OLD INLET AND OUTLET GASKETS ARE REMOVED AND REPLACED BE FORE INSTALLING THE NEW CAT WITH NEW BOLTS.
ABOUT $800 FOR THE PART AND A HOURS LABOUR.
AN MUFFLER SHOP SHOULD BE ABLE TO INSTALL A UNIVERSAL
CAT FOR LESS.
