I am gonna try and describe this as best as i can..when i put my foot on the pedal to accelerate, I hear this weird loud ssshhhhhh sound when I have the windows down and it seems to be on the right side of my truck. Originally, I thought it was the sound reflection from the exhaust pipe since it points in the direction but I just took the stock exhaust off and put a flowmaster muffler on with no pipe and I still hear the same noise..WHAT IS IT? I cant drive with the windows down it is so annoying
