It drones a bit but at 60mph it's totally fine. Remember tho I only have 2.47 gears so it only revs like 1800 on the highway with the 3spd auto. if you have a higher ratio I imagine it would be quite annoying on the highway. I'm not sold on the sound yet but I will see as time goes by. Today is the very first time I drove it with the glasspack.
how dose the Glass pack sound? also dose it drone out on the highway? i only ask because i have a 78 Mercury Marquis (same 6.6 L) and was thinking on livening it up a bit
