Fast Intentions exhaust is here! (continued)

The performance gain is very noticeable. There is a very big difference between stock and the pcs Tony installed. It was loud the first week and toned down a bit after that. I would say that the cold start SPL was reduced by about 10% from when it was newly installed. I was a little self conscious and concerned about waking up the neighbors with the cold starts for the 1st week or so. To me, starting up the car was better that a nice cup of joe. You will be tempted to drive the car at higher rpms and shift at around 3.5 to 4.5 and occasionally higher (really mostly higher). This combo for me just sounds amazing. I'm inside and really want to hear how it sounds outside. I'd probably have an accident in my pants if I were. On my drive to and from work driving under bridges and through the two tunnels (one of them a short truck route tunnel on southbound 5 - which unfortunately is one of the unsafest tunnels around CA), I simply smile and lust over the sound this exhaust delivers.
I find it amazingly loud and am extremely satisfied with the order.

Tone - Low tone growl at lower rpms, sexy burbling sound between 3k to 4k, roars when you floor it. Best way to describe it -- exotic or excitingly unique. Love this exhaust.

Volume - it is loud when you gun it, loud when down shift at midrange, loud when your at 60-70 mph at 2.5 to 3k rpm at 6 gear, down shift to 5th and she sings with an excitingly unique roar. Shift to 4th and your ears asks for more. It is loud when your next to bus, loud when your next to semi, and loud next to a Porsche. It is loud when you're under a bridge, even louder in a tunnel, which by the way is fun times when you down shift. It is loud when Synchro Rev Match kicks in on the downshift. FI + SRM + Tunnel =

This said, what do think would it be like in the cabin? Take a wild guess. Tony suggested 18's for a <30 % change for in cabin volume.
