This is just my opinion but bolting a full exhaust up to stock heads while you have the stock gears is not that great of an idea. You wouldn't really gain alot of HP from the headers because its the heads that are the bottleneck. Althought you might lose some torque. I wouldn't want to lose torque while running the stock gears in heavy vert. Definitely not on a car driven mostly on the street. I vote for the gears like some of the other guys said. If you skipped the headers and the cold air intake you could probably afford to have a set of gears installed and still spend about the same amount.
