Does anyone have the flowmaster 40 on their truck? I have a 3.9 v6.. how does it sound? Whats the difference between the regular 40 and the super 40? I just ordered it and im curious.

 

Nobody knows?

 

The regular 40 doesn't sound bad,I have one on my v6..Down side is the interior noise at highway speeds,It has a loud hum,but that could be the way my duals are ran.I am planning on getting rid of my converter and running my exhaust straight out the back instead of 45ed out the side,I"ll let you know how it sounds,I should have it done by next week.Good Luck ,Ramblin
