The key is increasing USABLE power and enhancing throttle response for great performance on the road course and street. Many times we have won races with lesser HP figures with increased torque and throttle response through the most critical portion of the rev range. This gets the car off the corners and onto the straights faster and on the street it REALLY increases the fun factor.
Thats what I am most pleased about with my current 2.5 development by far. The snap this combo has is unreal and the engine pulls to redline so fast that it can't be shifted fast enough... Tomorrow I am turning up the revs to 7,400 :-)
As for the exhaust note.... well our Clients are much more concerned with that than I am.. in fact I generally have to ask my employees and others about their thoughts on sound because it generally doesn't impact me that much.. Sound doesn't increase or efficiency or numbers, so it doesn't do much for me at all. :-)
The past two days on my 83 mile commute I averaged 34 MPG in the test car in the current state of tune... everything follows efficiency!
