Ear-splitting noise of Flowmasters? I have them on my 5.0 (ya, i know, a F***, but at least a pickup). I can downshift to 2nd at 70 mph, and engine rpm goes up to around 4000, and its not even close to earsplitting.
Flow's have a nice clean sound to them, and they don't pop like glasspacks do when you downshift, or let off of the gas. Also, remember that bigger pipes are better for hp, smaller for tq. I personally would never go smaller than 2 1/4 on anything I'll ever own.
