Know what ya mean.I remember the first time I fired my 55 up after the modifications.It was running right off of the headers,no pipes or mufflers.First drive was to the exhaust shop to have the Flowmaster system installed.About a 10 mile drive.A very loud ride.Went to pick it up the next day and boy did it sound sweet,exhausting thru the Flowmasters.Since then I have made many more improvements to it,but that first drive to the exhaust shop was the best.
