On what years would you suggest this upgrade?  I am aware that some years have one set of cats, and others have two.  Does this have any impact on what can be done?
I like the idea of the additional growl, and the additional h.p., but, I am leary about any exhaust change that causes the "drone" that I read about.  Have you experienced drone with your upgrade?
