Gas milage reduced

Installed Dynatech L/T headers with O/R x pipe and SLP Loudmouths. Has anyone experienced a major drop in gas milage.

You might want to have your car dyno'd. Check out the A/F's at WOT. (should be between 12.8 and 13.2 for best performance)

The adaptive learning feature in our cars will keep adjusting the A/F's for maximum efficiency (normal driving), generally takes a couple of hundred miles.
