For a mildy modified car, single 2.5 inch mandrel is the go for power and torque. As you go for more mods though, a twin system will sound better. X-pipe is a good thing. Headers will make a substantial difference as well.
I can only say that a custom programmed chip is the way to go. Unichip works very well on the XR8. That's my recommendation having fitted one to mine.
If your car is a 200, camshaft is a major issue. Send it on its way! 220 is better, however you will still find substantial gains in changing your camshaft.
So, my advice on order of priority is exhaust includinmg headers, unischip, then camshaft. Which basically follows what most tuners are offering in their packages.
