With a comprehensive list of full Titanium catback exhausts available, I was able to further narrow my requirements according to my preferences in no particular order:

Weight Matters!

Since my days as a drag racer, I knew that shedding weight here and there can add up quickly, even if it was only a few pounds.  It is no secret that a lighter car accelerates and stops quicker in addition to handling better.  Plus, gas mileage on a daily driven car will improve albeit by a small percentage (more from less restriction than weight savings, but every little bit counts rights?).  As such, the lighter the titanium catback exhaust, the higher it ranked.

Sound

A great exhaust produces a distinctive, not too ricey exhaust note.  It could not be too loud that I would have to worry about my neighbors complaining when I leave or return to my house.  But the titanium exhaust had to be more aggressive in tone than the stock exhaust.
