Yes and no, to the Cat question.
In Federal emission states you can use just about any ODB2 approved high Flow CAT. In states that use the California standard you have to get a replacement that is approved by CARB (which very few are). You are stuck (in most cases) with using OEM CATs in California and the 4 other states that use the CARB standards.
The sulphur smell is usually caused by very lean fuel mixture. Many of the new trucks I've seen (smelled) have this problem. They have to idle at this lean mixture to pass emissions. Passing emissions is more important than stinking. Although, I would have a mechanic run an emissions test to see what is going on with the engine and if it is running within normal parameters.
