Also interested in some additional comparisons to the FI in terms of sound (I have the 18'' resonators). You said its a bit loud on cold start, how does it compare to your FI cold start? At normal cruising speeds, how loud is it inside the car, and how is the drone at highway speeds compared to FI? I would love to eliminate the hiss my exhaust produces and your write-up has me thinking of a change. Repped for the great review.
