search sector 111 on youtube. Shinoo posted a nice video after the install. As far as drone there is none. The difference is barely noticeable at freeway speed. I do appreciate that these things are rather subjective, but I had a Lotus factory stage 2 on my first 2005 Elise and it was aweful on the freeway. I have now had 2 larini's one on my Elise SC and now on my Evora SC and they are very good. They give you the exotic sound, but are very tame when you are off the gas. I don't track my car so the performance is really not an issue, but the sound is just so much more fun. I have an Audi R8 stock that sounds great, but honestly I prefer the Evora S with the Larini and I never thought I would say that about a V6 vs a V8. The nice thing is that you can "modulate" the noise a bit by either deleting the resonator pipe (often referred to as a "decat pipe") or not. Louder if you replace it with a straight pipe and quieter if you don't. One final comment, I would be cautious about making judgements on the sound when someone is standing behind the car. The "value" of the new exhaust is what you hear inside when driving--both with windows up and down. Fortunately with San Diego weather it is mostly windows down, but it is nice then when I am on the freeway cruising, I put the windows up and the car cruises along in comfort and you can listen to the stereo without issue.
