I really think you would like the Dinan axleback with some test pipes. Power, little to no smell, and good, manageable sound (no drone on the freeway).
It was one of the combos I was considering but I didn't dig the look of the Dinan mufflers, and after adding up mufflers + x-pipe + tune it was getting above the budget I had allocated for this exercise. For now I'll give the Eisenmann some more time before switching to something else.
