Rotten egg smell

[Razorback]

Our exhaust smells like rotten eggs, BAD, does that mean the cadilac converter is plugging up.

Cat needs to be replaced and is on it's way out

I concur....Cat going bad.

And I wouldn't change it without also finding the reason it went bad in the first place, such as running rich from a bad thermostat. Have you had the Check Engine light on? Is the temp gauge steady at straight-up 210?

No engine lights, the truck just turned 40,000 miles , it still has a waranty on it, its a 08 trailblazer, some of you has seen the one iam talking about.

And I quote-from the EPA:

B. DESIGN AND DEFECT WARRANTY

The Design and Defect Warranty covers repair of emission related
parts which become defective during the warranty period. The Design
and Defect warranty for model year 1995 and newer light-duty cars and
trucks is outlined below:

Design and Defect Warranty Coverage for 1995 and newer light-duty
vehicles:

* Emission control and emission related parts are covered for the
first 2 years or 24,000 miles of vehicle use; and

* Specified major emission control components are covered for the
first 8 years or 80,000 miles of vehicle use.

Seems to me like the cat would be a specified major emission control component
