YOU KNOW THE MECHANIC SAYS THE SAME THING
BUT I COULD SWEAR IM DRIVING THE SAME WAY. I DO ALOT OF HIGHWAY DRIVING AND AM USALLY IN THE 70-80 MPH RANGE, GUESS I WILL HAVE TO MAKE A EFFORT TO DO 60 -65 FOR A LITTLE WHILE TO SEE BUT I DONT KNOW, IT SOUNDS GOOD BUT I WOULD STILL LIKE A EVEN DEEPER SOUND BUT MIGHT BE ASKING TO MUCH FOR A 4 CYLINDER
