I think it is worth it. You will notice most of the difference in performance while in sport mode, not so much in D but there is a difference.
intake + exhaust + pulley is the best start IMO...
+1... just not in that order.
Exhaust first then the intake. The pulley doesn't help the car breathe, so you can do it at any time. Some people claim that they felt the biggest difference with the pulley... even more than an intake and exhaust (but they probably bought all their parts from RRM).
If you do the intake first, it's like your car is breathing through it's mouth and out of it's nose. I did the intake first and I do notice a difference, but I wish I did the exhaust first to get that out of the way. I still can't decide :(
