Exhaust will get you more. The intake is the same as a GT's up to the throttle body. A correctly sized exhaust (2"-2.25") will net you 12-16 hp. Going too large on the exhaust will lose you both hp and torque.

Metal CAIs perform no better than a drop in K&N Filter. That said, plastic CAIs like from DeMolet & K&N have gains of 7-12 hp. As far as bang for the buck, it's about equal.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
