Thanks for the responses. What High Flow Cats did you end up getting? What brand and are they ceramic or metallic.
I am pretty sure this will help.

I bought Pypes high flow cats from AmericanMuscle.com. They are ceramic. I think you only need the metallic if you are supercharged.

Also, I made another post about this earlier, but the long and short is that they wont quiet down your exhaust volume but they do change the way it sounds for the better. A more controlled sound in my opinion.

No Riptide it is not a sulfer smell at all. Just a overly rich gas smell. Its because of the cams.
Before the cams without cats it was a slight smell but not like this.
Cats will help for sure.
