Looking for the best type of cat back for my GTO - 4" tail exhaust without dumping large sums of money into it - any ideas out there anyone?

...I'm taking it that you own a Stainless Works Exhaust System. Do you have the system with the:
>Dual Chambered Pipes?...
or
>Dual Turbo Mufflers?
Is this system obnoxiously loud, or just deeper than factory?

I like the sound of my 04's factory system (even the popping while downshifting) but want a lil' more HP. Does this system have any renosance in the cabin?

Thanks!
