I have a video too I made a few years back of me being a fruitcake, but you can hear the sound pretty well.
When BC released this exhaust in jp I had a hard on for it, and ordered it from *some lame vendor* who got it to me 6 months later.
I am with brian on the silencer, it is big, and lame, mine ended up shooting itself out of the car on the 605S interchange to 405S.
I had a knock off down pipe, but cut it and re-welded it for ground clearance, also had the trans mount tight. My spec II never rubbed. Build quality is beyond beyond good.

Steve Shadows had the Spec II for a little. He got over it and got the CS quite exhaust and made more power on the dyno than the spec II.
So all in all, if you want a really well built wanna be "boso" exhaust, for sure get it. Other wise there are less expensive, less conspicuous, and more power systems out there.
Oh.
I swapped it onto my KA car for a week, because I got an exhaust ticket in the red car. NA KA sounded dumb as retarded babies with the spec II.
