Really depends on your age more than anything. This is a theory I am working on. Me being all of 22, I wanted more sound than the stock system was able to give me. Looks were what really sold me on the Bassani, and once the res tips were out, I have no regrets. You get used to the sound after time and don't really even notice it.
Heres a couple of pics to help persuade youin the ways of the Bassani :), sounds like you ahve already made up your mind, but it never hurts to "seal the deal".
Here is my Dyno plots, stock then with the addition of a KKM w/ Mik's Heatshiled and my Bassani (- the res tips)
If you have any more questions or what have you, feel free to drop by my pics page or drop me an e-mail (Both are in the sig)
