I totally agree with what you said Matt. Baseline is a must for comparison, but done on the same day. If I had the time, I would have. Regardless, no individual has come on here to state/prove they did a stock run before putting on their exhaust except for the companies selling their pipe. So many are in the same boat as me. My goal was just to see what my car puts out. Maybe some of the guys will take their car to the dyno. Hey if you have the time on sat, I know johnny would love to put your car on his dyno.
