personally, my opinion on the matter is that for even better feedback from the engine you should have a relatively loud exhaust, obviously not the most pleasant idea. my car is fairly loud at cruise, mostly because im too cheap to buy a muffler and i can easily tell how much load i have on the engine just by the exhaust note. it will have a certain resonance, but when you ease off it will go sharp, and if you push it a little it goes flat, easy way of knowing.
