Flowmaster 40 series numbers
I know prior to installing my dual exhaust I searched this board over and over to find some actual numbers on what it would do. Here are my findings, I have a 2000 F-150 Lariat 4x4 5.4L with 40,000 miles. I have the cold air intake system with the K&N filter and a tonneau. Prior to installing the exhaust my truck ran a 17.49 and 17.42 actual 1/4 mile. After the exhaust I ran a 17.35 and 17.32.
Hope other people with find these numbers helpful in making decisions. The truck does sound a ton better and looks really cool as well.
