Installation was a quick process; the header dropped in from the top of the engine compartment easily with no clearance problems.

We weren't able to re-attach the oxygen sensor wire bracket due to the O2 bung's position farther down than the stock header's location. Lowered cars beware!

Dyno Notes
The factory belts were badly worn and loose on the car, and we believe this could have accounted for a loss in friction between them and the factory pulleys. With the new belts strung on the UR pulleys, the friction was increased and a more accurate power reading was made possible. We believe the pulleys could have made more power if the belts were not loose to start with
