True the stock unit is designed to do the job but if I put a free-er flowing exhaust and use an engine tuner, wouldn't it help to upgrade the intake too?

The engine can only consume so much air at any one time, per unit of fuel (*natural aspiration only). The key with any intake (or exhaust for that matter) is maintaining air velocity. While an upgraded intake will flow more... if the area of the intake is larger, your velocity is reduced. Changing the parameters with a tuner, will not warrant the need for an intake upgrade (but its a common upgrade). To each their own.
With an exhaust upgrade..... the buzzword people know is 'backpressure'. Its a bit of a misnomer. What you should only be concerned with on exhaust is... you guessed it... exhaust velocity. The larger the exhaust pipe? Well of course you lose the 'backpressure', but you also lose some velocity. Also, the larger the pipe you go, the higher your power curve will move (up in the RPMs).
^^^ With that said...... the power gained, lost, or moved with an exhaust upgrade is negligible. I upgrade mine, because they sound better .
Yup, the exhaust and the intake make the car sound real nice, but they aren't going to do anything for performance or MPG. The engine will pull in the amount of air it needs regardless of whether the it has a stock or aftermarket intake. That being said, I likes my Volant...for now. That Roush supercharger is calling me...
If you want performance improvements go with a programmer.
