I have a Bassani exhaust on my 04 and love the sound. Magnaflow also makes great sounding exhaust. Others may disagree, but in my opinion if you are only running a pulley and Predator tune the stock intake is fine. Adding an aftermarket intake will increase the blower whine and sound great but you will not see any performance enhancement. If you decide to go ahead and change out the intake, stay away from the open filter style. Drawing hot air from under the hood can actually cost you horsepower at the rate of 1% loss for every ten-degree rise in intake temperature.
