anybody know why we never got the Monte Carlo Blue. That is by FAR my favourite color..

 

Any info on borla exhaust, I might be interested in that.

 

I can't give you a direct answer to your question but before Borla actually made a product for the S2000, it was believed that they provided the components for Neuspeed to make theirs for this car. If you go to the Neuspeed sound file, I think you will get a fairly good idea of what a Borla will sound like.
ps. I had a Neuspeed V.2 just before my current Fujitsubo and I loved that exhaust. It's just that it was getting a bit too loud for me after being on the car for nearly 4 years.
