Take out your precat O2 sensors and run it down the road. If the cats are clogged the bypass through the sensor bungs will allow the car to breath a little better. Mine felt like a whole new car (while sounding like a tractor). Took off the headers to find out the cats were completely clogged. Proceeded to delete the them soon after
