I saw a dyno result that showed about a ten HP increase, the exact increase fluctuated depending on where you were in the RPM band, ten was the highest. This was for muffler only no headers. I don't know if the data was accurate or not. Most flashtunes I have seen are saying 10hp 10 torque for the 2.5 motor, again I don't know it that's true. IMHO, the butt dyno is really all that matters...
